Abstract

The invention discloses a radio frequency stealth-based airborne networking radar radiation parameter joint optimization method, which belongs to the technical field of radar signal processing. The airborne networked radar system obtains the target RCS and its distance relative to each radar transmitter and receiver, with the goal of minimizing the radio frequency stealth performance indicators of the airborne networked radar, and the target tracking error, detection performance and The radar radiation parameter is a constraint condition, establishes an airborne network radar radiation parameter optimization model based on radio frequency stealth, and jointly optimizes radiation parameters such as radar transmitter selection, sampling interval, dwell time and transmission power, and utilizes the model of the inventive method The obtained optimal radar radiation parameters can effectively improve the radio frequency stealth performance of the airborne networked radar system in the target tracking mode under the condition of satisfying certain target tracking accuracy and target detection performance.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, in particular to a radio frequency stealth-based airborne networking radar radiation parameter joint optimization method. Background technique [0002] Aircraft Radio Frequency (RF) stealth technology, as an important active stealth technology, is an important means to counter the enemy's passive detection system and ensure that fighter jets and their formations find, strike and destroy the enemy first. Specifically, aircraft radio frequency stealth technology refers to the stealth technology of airborne radar, data link, altimeter and other airborne active electronic equipment to resist interception, sorting, and identification of enemy passive detection systems, so as to reduce the risk of passive detection systems. The interception probability and interception distance are the goals, so as to improve the aircraft's battlefield survivability and penetration capability. Aircraft...
