Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] refer to figure 1 , is a flow chart of the airborne radar radio frequency stealth performance evaluation method of the present invention. This airborne radar radio frequency stealth performance evaluation method comprises the following steps:

[0022] Step 1, set multiple identical intercepting receivers within the irradiation range of the airborne radar, each intercepting receiver is located on a detection target of the airborne radar; use the airborne radar to transmit signals outward, each intercepting receiver It is used to receive the signal emitted by the airborne radar; the detection equation of the airborne radar and the detection equation of each intercepting receiver are obtained.

[0023] Specifically, in step 1, in order to illustrate the relationship between the detection distance of the airborne radar and the interception distance of the intercepting ...

Abstract

The invention belongs to the technical field of electronic countermeasure, and particularly relates to an airborne radar radio frequency stealth performance evaluating method. The airborne radar radio frequency stealth performance evaluating method comprises the following steps of obtaining a detection equation of an airborne radar and a reconnaissance equation of each intercept receiver; obtaining the transmitting peak power PT of the airborne radar; 3, according to the transmitting peak power PT of the airborne radar and the reconnaissance equation of each intercept receiver, obtaining the power Pi of a signal received by the corresponding intercept receiver; obtaining a calculation formula of the probability pi of the corresponding beam successfully intercepted by at least one intercept receiver when the airborne radar transmits one beam; according to the power PI required by the signal detected by each intercept receiver, and the power Pi of the signal received by the corresponding intercept receiver, obtaining the probability pi of the corresponding beam successfully intercepted by at least one intercept receiver when the airborne radar transmits one beam; according to the value of pi, evaluating the radio frequency stealth performance of the airborne radar.

Description

technical field [0001] The invention belongs to the technical field of electronic countermeasures, in particular to a radio frequency stealth performance evaluation method of an airborne radar. The present invention mainly relates to the problem of how to quantitatively analyze the radio frequency stealth performance of airborne radar, which can be used in the actual battlefield environment to analyze the interception rate of signals, so as to evaluate the radio frequency stealth performance of airborne radar, and guide the radio frequency stealth performance of aircraft. Stealth system design. The invention can comprehensively consider various factors affecting the radio frequency stealth performance, and provide quantitative analysis. Background technique [0002] Nowadays, radar is facing threats from low-altitude penetration, stealth technology, electronic countermeasures and anti-radiation missiles. How to improve the survivability of radar in the current war has becom...
