摘要
讨论了雷达信号处理中的自适应动目标显示技术，即雷达回波信号中的运动杂波的抑制问题．针对常见的功率密度函数为高斯型的运动气象杂波，寻求一种基于最大平均改善因子准则的简便实用的快速计算方法及实时实现技术．实际系统测试表明，该方法运算量小，易于实现，对高斯型及近似高斯型运动杂波具有良好的抑制效果，对相对带宽小于４％的动态杂波，动目标显示系统的改善因子可以达到３５ｄＢ以上．
The adaptive MTI realization techniques are discussed. A simple, practical and fast algorithm based on the maximum average Improvement Factor criterion as well as its real time approach has been achieved for the rejection of moving weather clutter which has a power spectrum density function of the Gaussian type. This method has been applied to the signal processing module of a solid state phased array radar. The test results show that this approach needs less computation burden and has a better rejection effect for the Gaussian or near Gaussian type of moving clutters. For moving clutters with a relative bandwidth of less than 4%, an improvement factor greater than 35 dB has been achieved.
