根据机载雷达回波信杂比很小的特点 ,提出了一种基于功率倒置法的地杂波抑制方法。该方法利用单脉冲雷达空间双路接收的特点 ,采用时 -空二维联合处理的方法对回波信号进行处理。理论分析和仿真结果表明 ,该方法信杂比改善性能优于AMTI等一维杂波抑制方法。并且由于其自适应权采用功率倒置法准则求得 ,计算量大大低于采用最大输出信杂比准则的一般时 -空二维处理 ,因此 ,该方法是一种具有工程意义的机载雷达杂波简化时空二维处理方法
According to the characteristics of small signal-to-noise ratio of airborne radar echo, a ground clutter suppression method based on power inversion is proposed. The method takes advantage of the dual reception of monopulse radar space, and adopts the method of time-space two-dimensional joint processing to process the echo signal. Theoretical analysis and simulation results show that the proposed method has better signal-to-noise ratio (SNR) improvement than one-dimensional clutter suppression such as AMTI. Because the adaptive power is calculated by the power inversion method, the computational complexity is much lower than the general time-space two-dimensional processing using the maximum output signal-to-noise ratio criterion. Therefore, this method is an engineering airborne radar jammer Wave simplified spatio-temporal two-dimensional approach
