摘　　要：介绍了机载相控阵雷达STAP技术的基本原理,提出一种针对目标保护的相干散射干扰方法。将接收到的雷达信号用数字射频存储器(DRFM)存储,经频率调制形成密集的相干脉冲串干扰信号,使得最优二维频率响应,在目标所在的距离单元上除了真实目标外,还存在多个欺骗假目标。理论分析和仿真结果表明了该方法的有效性。The basic principle of STAP of airborne phased arrays radar is introduced.Then a method of coherent scattering jamming for target protection is proposed.Radar signal is stored by digital radio frequency memory（DRFM） and frequency modulation is done to form dense coherent pulses jamming signal,which is transmitted towards the protected target directly.Except for the real target,several cheating false targets exist in the range bin of optimal two-dimension frequency response.Theory analysis and simulation results are presented to verify the effectiveness of the proposed method.
