摘要

本文分析了天基雷达平台上稀疏阵列的HRWS和GMTI性能。成像STAP (Imaging STAP, ISTAP)用于杂波消除和运动参数估计，多通道信号重构则在MMSE意义下完成。结果表明，在不需要在航天器上增加额外硬件的情况下，稀疏阵列可以改善GMTI。最小冗余阵列提供了HRWS/GMTI性能的最佳折衷。

Performance analysis of HRWS/GMTI for space-based SAR using sparse arrays

In this paper, we analyze the HRWS and GMTI performances of sparse arrays mounted on a space-based radar platform. Imaging STAP (ISTAP) is employed for clutter cancellation and estimation of motion parameters, while multichannel signal reconstruction is done in the MMSE sense. It is demonstrated that sparse arrays lead to improved GMTI, without the need for additional hardware on the spacecraft. A minimum redundant array provides the best compromise of HRWS/GMTI performances.
