| 摘 要： | 该文提出了两种利用基于导数更新(DBU)的双基机载雷达杂波距离依赖性补偿新方法，分别以接收载机方向图主瓣方向的接收斜距和接收载机方向图主瓣方向的接收俯仰角余弦为更新变量，利用该方法对回波数据进行补偿后，能够有效降低双基机载雷达杂波的距离依赖性，进而大大提高空时自适应处理 (STAP)的地面动目标检测(GMTI )性能。仿真数据处理结果证明了所提方法的有效性。

| Abstract: | Two new methods to compensate clutter range dependence for bistatic airborne radar are proposed in this paper. These methods are called DBU (Derivative Based Updating). The receiving slope distance and receiving elevation angle cosine in the direction of the main lobe of beam pattern are respectively utilized as updating parameter. The methods can mitigate the clutter range dependence, and improve the performance of Space-Time Adaptive Processing (STAP) in Ground Moving Target Indication (GMTI). The results of computer simulation show the effectiveness of the methods. |
