Significant Accounting Policies and Recent Accounting Standards (Policies) [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Harris Corporation and its subsidiaries. As used in these Notes to Condensed Consolidated Financial Statements (Unaudited) (these “Notes”), the terms “Harris,” “Company,” “we,” “our” and “us” refer to Harris Corporation and its consolidated subsidiaries. Intercompany transactions and accounts have been eliminated. The accompanying condensed consolidated financial statements have been prepared by Harris, without an audit, in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, such interim financial statements do not include all information and footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for annual financial statements. In the opinion of management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows for the periods presented therein. The results for the quarter ended September 28, 2012 are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. The balance sheet at June 29, 2012 has been derived from the audited financial statements but does not include all of the information and footnotes required by U.S. GAAP for annual financial statements. We provide complete financial statements in our Annual Report on Form 10-K, which includes information and footnotes required by the rules and regulations of the SEC. The information included in this Quarterly Report on Form 10-Q (this “Report”) should be read in conjunction with the Management's Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 29, 2012 (our “Fiscal 2012 Form 10-K”). In the third quarter of fiscal 2012, our Board of Directors approved a plan to exit our cyber integrated solutions operation (“CIS”), which provided remote cloud hosting, and to dispose of the related assets, and we reported CIS as discontinued operations beginning with our financial results presented in our Quarterly Report on Form 10-Q for the third quarter of fiscal 2012. In the fourth quarter of fiscal 2012, our Board of Directors approved a plan to divest Broadcast Communications, which provides digital media management solutions in support of broadcast customers, and we reported Broadcast Communications as discontinued operations beginning with our financial results presented in our Fiscal 2012 Form 10-K. Both CIS and Broadcast Communications were formerly part of our Integrated Network Solutions segment. Our historical financial results, except for disclosures related to our cash flows, have been restated to account for CIS and Broadcast Communications as discontinued operations. For additional information regarding discontinued operations, see Note B — Discontinued Operations. Except for disclosures related to our cash flows, or unless otherwise specified, disclosures in this Report relate solely to our continuing operations. The preparation of financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and these Notes. Actual results could differ from those estimates and assumptions.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In the first quarter of fiscal 2013, we retrospectively adopted an accounting standard issued by the Financial Accounting Standards Board (“FASB”) for the presentation of comprehensive income in financial statements. The adoption of this standard resulted in the presentation of the components of net income, components of other comprehensive income and total comprehensive income in two separate but consecutive statements. The adoption of this standard only changed how we present comprehensive income and did not impact our financial position, results of operations or cash flows. In the first quarter of fiscal 2013, we adopted an accounting standard issued by the FASB that simplifies how entities test goodwill for impairment. This standard gives entities the option to assess qualitative factors first, to determine whether it is necessary to perform the two-step quantitative goodwill impairment test for their reporting units. Under this standard, an entity is not required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not (a likelihood of more than 50 percent) that its fair value is less than its carrying amount. Additionally, this standard includes examples of events and circumstances that an entity should consider in conducting the qualitative assessment. The adoption of this update did not impact our financial position, results of operations or cash flows.
Fair Value Measurements, Recurring Basis	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.
Evaluation of performance and intersegment sales policy	The accounting policies of our business segments are the same as those described in Note 1: “Significant Accounting Policies” in our Fiscal 2012 Form 10-K. We evaluate each segment's performance based on its operating income or loss, which we define as profit or loss from operations before income taxes excluding interest income and expense, royalties and related intellectual property expenses, equity investment income or loss and gains or losses from securities and other investments. Intersegment sales are generally transferred at cost to the buying segment and the sourcing segment recognizes a profit that is eliminated. The “Corporate eliminations” line item in the tables below represents the elimination of intersegment sales and their related profits. The “Unallocated corporate expense” line item in the tables below represents the portion of corporate expenses not allocated to our business segments.

The preparation of financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and these Notes. Actual results could differ from those estimates and assumptions.

Adoption of New Accounting Standards

In the first quarter of fiscal 2013, we retrospectively adopted an accounting standard issued by the Financial Accounting Standards Board (“FASB”) for the presentation of comprehensive income in financial statements. The adoption of this standard resulted in the presentation of the components of net income, components of other comprehensive income and total comprehensive income in two separate but consecutive statements. The adoption of this standard only changed how we present comprehensive income and did not impact our financial position, results of operations or cash flows.

In the first quarter of fiscal 2013, we adopted an accounting standard issued by the FASB that simplifies how entities test goodwill for impairment. This standard gives entities the option to assess qualitative factors first, to determine whether it is necessary to perform the two-step quantitative goodwill impairment test for their reporting units. Under this standard, an entity is not required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not (a likelihood of more than 50 percent) that its fair value is less than its carrying amount. Additionally, this standard includes examples of events and circumstances that an entity should consider in conducting the qualitative assessment. The adoption of this update did not impact our financial position, results of operations or cash flows.

Fair Value Measurements, Recurring Basis

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:

• Level 1 — Quoted prices in active markets for identical assets or liabilities.

• Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means.

• Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Evaluation of performance and intersegment sales policy

The accounting policies of our business segments are the same as those described in Note 1: “Significant Accounting Policies” in our Fiscal 2012 Form 10-K. We evaluate each segment's performance based on its operating income or loss, which we define as profit or loss from operations before income taxes excluding interest income and expense, royalties and related intellectual property expenses, equity investment income or loss and gains or losses from securities and other investments. Intersegment sales are generally transferred at cost to the buying segment and the sourcing segment recognizes a profit that is eliminated. The “Corporate eliminations” line item in the tables below represents the elimination of intersegment sales and their related profits. The “Unallocated corporate expense” line item in the tables below represents the portion of corporate expenses not allocated to our business segments.
