机载X波段雷达的双通道空时自适应处理的试验研究

Experiment Research of Two-channel Space & time Adaptive Processing on X-band Airborne Radar

本义阐述了空时两维自适应处理的基本原理、方法,给出了影响GMTI性能的关键因素及解决办法,介绍了具有两偏置相位中心天线的机载X波段雷达的实验情况,对实际回波用MTD、ADPCA级联MTD和PI-STAP级联MTD三种方法进行了处理。

The paper expatiates the basic principle and method of two-dimensional (space & time) adaptive processing; the key factors, which affect the performance of GMTI, has been found out and resolved; introduces the circumstances about experiment of X band airborne radar which has two-displace Phase center antenna; gives the experiment results after processing actual echo by three methods which are MTD and ADPCA cascade MTD and PI-STAP cascade MTD.
