Abstract

The invention discloses an airborne networking radar radiation parameter joint optimization method based on radio frequency stealth, which belongs to the technical field of radar signal processing. For an airborne networking radar system composed of a plurality of airborne radar transmitters and a plurality of airborne receivers, the airborne networking radar radiation parameter joint optimizationmethod is characterized by acquiring a target RCS and a distance from the target RCS to each receiver relative to each radar transmitter, regarding minimization of an airborne networking radar radiofrequency stealth performance characteristic index as a target, regarding target tracking errors, detection performance and radar radiation parameters as constraint conditions, establishing an airborne networking radar radiation parameter optimization model based on radio frequency stealth, performing joint optimization on radiation parameters such as selection, sampling interval, dwell time and transmission power of the radar transmitters, and effectively improving the radio frequency stealth performance of the airborne networking radar system in a target tracking mode by means of the optimalradar radiation parameters obtained by utilizing the model established according to the method under the condition of satisfying certain target tracking precision and target detection performance.

Description

Technical field [0001] The invention belongs to the technical field of radar signal processing, and specifically relates to a joint optimization method for radiation parameters of airborne netting radar based on radio frequency stealth. Background technique [0002] As an important active stealth technology, aircraft radio frequency (RF) stealth technology is an important means to counter the passive detection system of the enemy, and to ensure that the fighters and their formations discover, strike and destroy the enemy first. Specifically, aircraft radio frequency stealth technology refers to the stealth technology that airborne active electronic equipment such as airborne radar, data link, and altimeter resists interception, sorting, and identification by the enemy's passive detection system, so as to reduce the passive detection system. The interception probability and interception distance are the targets, thereby enhancing the aircraft's battlefield survivability and penetr...
