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...
