A Clutter Samples Increase Jamming Method to Airborne STAP

Proposed a clutter samples increase non-homogeneous jamming method to airborne space-time adaptive processing. The method uses digital radio frequency storage as a realization method. First, the number of interference samples is obtained by estimating the radar range resolution and the target radar interference distance, and then modulate jamming information with non-homogeneous clutter background environment parameters on the radar clutter echo, include signal amplitude, interference phase and Doppler frequency. Lastly, with the Clutter echo in protected areas for the pollution of the co-variance matrix by STAP, the method can reduce the STAP processing target detection ability. The validity is verified by the simulated processing results of a real airborne radar data.
