Simulation of Dynamic Clutter and Signal Processing of Passive Detection Based on Non-cooperative Airbone Radar Emitter

The passive detection system based on non cooperative airborne radar transmitter separates the transmitter and receiver and arranges them on different platforms. The transmitter can be an early warning aircraft, and the receiver can be equipped with high-resolution radar. The system is flexible, the signal interception probability is low, and the anti electromagnetic interference ability is strong. However, this system will make the clutter change with the moving state of the emitter. To solve this problem, a method of dynamic clutter simulation is proposed according to the characteristics of the clutter covariance matrix, and a non-cooperative radar target detection system is designed to deal with the dynamic clutter. The results show that the location, velocity, and angle of the radiation source and target can be extracted by the non-cooperative radar radiation source-target detection system after clutter dynamic processing.
