摘    要:距离模糊杂波和杂波数据样本距离非均匀对机载双基地雷达杂波STAP性能影响严重,文章提出了一种正交投影-多普勒频移算法以实现模糊杂波抑制和非均匀性补偿.该算法首先基于待检测距离环杂波空间和时间多普勒频率信息构造空间和时间投影矩阵,重构杂波数据,消除模糊杂波,然后利用多普勒频移对杂波样本间距离非均匀性进行补偿.仿真表明:该...

关 键 词:机载双基地雷达  空时自适应处理  距离模糊  距离非均匀  正交投影  多普勒频移

Abstract:As the performance of STAP of airborne bistatic radar is seriously affected by the range ambiguous clutter and the range nonhomogeneous peculiarity of clutter data samples,an orthogonal projection-Doppler warping method was put forward to cancel the range ambiguous clutter and compensate the nonhomogeneity between clutter data samples.Firstly,this method constructed a space and a time orthogonal projection matrix,which based respectively on the space and the time Doppler frequency of the clutter which retur...
