The wide-band noise jamming method fails to conceal the azimuth information of the target in the power condensation pattern. Therefore

a scattered-wave jamming method is proposed. The fake clutter signal is generated by scattering radar signal with Doppler shifting to the certain areas from jammers. The jamming signal acquires space-time coupling and is continuous both in space domain and time domain. The trajectory of jamming space-time power spectrum is controllable. The effect of radar target detection is analyzed by deriving the mathematic model of jamming signal. Furthermore

according to the Doppler trace feature and the Doppler isoplethic

curves characteristic of the jamming signal

the estimation algorithm of the clutter and jamming covariance matrix eigenvalue number is proposed. The simulation results indicate that the shape of jamming space-time power spectrum is similar to bias

which leads to the improvement factor of STAP radar appearing more than one not
