System and method for screening parameters intercepted by passive radar sensor

The invention provides a system and method for screening parameters intercepted by a passive radar sensor, and belongs to the field of unmanned aerial vehicle load parameter screening, and the system comprises a passive radar sensor, a three-dimensional turntable, a turntable servo driver, a data processing platform, a vector signal source and a radiation antenna. The data processing platform is used for generating a test parameter matrix; passive radar sensors are sequentially arranged according to array element data in the test parameter matrix; the data generation module is also used for generating orthogonal digital baseband data by using the test parameter characteristics of the radiation source to be simulated; the selection module is also used for selecting the array element data in the test parameter matrix corresponding to the minimum interception time value as the optimal interception parameter; compared with a traditional mathematical analysis model, the method has the advantages that the obtained
