摘　　要：针对现代地基雷达传统方法抑制杂波不彻底的情况,根据空时二维信号处理技术(STAP)的特点和发展趋势,提出了将空时二维信号处理技术应用于地基二维相控阵雷达中的设想。根据地基雷达运动杂波的特点,在考虑误差情况下,对运动杂波二维耦合谱进行分析和仿真;初步构想了应用STAP的地基雷达无源干扰抑制结构,并对全空时自适应处理器抑制运动杂波进行仿真分析。结果表明,空时二维信号处理抑制运动杂波可以取得很好效果。In view of circumstance that the clutter could not be suppressed completely by modern ground-based phased array radar using traditional approach, an idea of applying space-time adaptive processing（STAP） technolo- gy in ground-based radar is presented on basis of characteristics and development trends of STAP. According to characteristics of ground-based radar moving clutter, and in case of considering error, two-dimensional coupling spectrum of the moving clutter is analyzed and simulated. The passive interference repression structure of applying STPA on ground-based radar is conceived preliminarily. And usage of the all space-time adaptive processor to sup- press moving clutter is simulated and analyzed. The results indicate that using space-time adaptive processor could achieve excellent effect in suppressing moving clutter.
