A screening system and method for passive radar sensor interception parameters

Abstract

The invention provides a screening system and method for parameters intercepted by passive radar sensors, belonging to the field of screening parameters for unmanned aerial vehicles. The system includes: passive radar sensors, three-dimensional turntables, turntable servo drivers, data processing platforms, vector signal sources and radiation Antenna; wherein, the data processing platform is used to generate a test parameter matrix; and sequentially set the passive radar sensor according to the data of each array element in the test parameter matrix; it is also used to generate orthogonal digital baseband data using the test parameter characteristics of the radiation source to be simulated ; It is also used to select the array element data in the test parameter matrix corresponding to the minimum value of the interception time as the optimal interception parameter; compared with the traditional mathematical analysis model, the parameters of the passive radar sensor obtained by the present invention are more referential; The use of physical tests to consume UAVs reduces test costs and cycle times; moreover, the test parameter matrix provides parameters of several passive radar sensors, and the data coverage is comprehensive.

Description

technical field [0001] The invention belongs to the field of screening of load parameters of unmanned aerial vehicles, and more specifically relates to a screening system and method of parameters intercepted by passive radar sensors. Background technique [0002] Anti-radiation drones equipped with passive sensors are an effective way to suppress and destroy ground-based radars. The passive radar sensor can only switch to the attack program after intercepting the target signal, so the interception time becomes the key issue when attacking the time-sensitive target. In order to reduce the interception time, the interception probability of passive radar sensors must be studied. [0003] Due to the limitation of size, weight and power consumption, the passive radar sensor of UAV is usually set as a search intercept receiver, which needs to search for target signals in the air domain, frequency domain, time domain and other parameter domains, and the intercept probability becom...
