摘要
本文研究了机载预警雷达采用非正侧面阵时主杂波区性能改善的问题．首先对机载雷达非正侧阵主杂波谱宽进行了分析．其次研究了文献［1］的先滤波再自适应处理的方法，并从实用化角度提出了改进的方法，最后对改进方法进行了详细的理论分析与计算机模拟研究．
The mainbeam clutter spectra for airborne early warning(AEW)radar with non-side ways looking array(placed on aircraft turned in azimuth)are analyzed firstiy.In order to improve the system perfor mance near the mainbeam clutter region of this radar,the”filter-then-adapt”approach presented by Brennan is introduced and studied.For reducing the sampling and computational requirements,a modified space-time joint adaptive processing approach is proposed and analyzed.
