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:该算法对任意双基地几何场景都有良好适应能力

可有效提高机载双基地雷达STAP性能.

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 returned from the nonambiguous range loop

and used these matrixes to form a new clutter data matrix.Secondly

it gave the new clutter data a Doppler warping to reduce the range nonhomogeneous of samples.The simulation indicates that this method greatly improves the performance of STAP under various bistatic geometries.
