| 摘 要： | 分析了机载火控相控阵雷达的地杂波的空时二维分布特点,提出了一种基于DPCA(displaced phase center antenna)相位补偿的降维∑△-STAP方法,分析了其平台运动补偿的基本原理,对其低速动目标检测性能进行了计算机仿真分析,并将其性能与运算量同3DT-∑△-STAP进行了比较.结果表明,该处理方法不仅具有接近于3DT-∑△-STAP的杂波抑制性能,而且运算量远低于3DT-∑△-STAP,因此是机载火控雷达机上处理的一种优选方案.

| Abstract: | The space-time distribution characteristics of ground clutter returns in airborne fire-control radar are analysed. A reducedrank -STAP technique based on DPCA phase compensation is presented, and its principle of platform motion compensation is analyzed. The simulation results are given, and its GMTI performance is compared with that of 3DT-STAP. It is shown that the GMTI performance of this method is nearly as excellent as that of the latter but much lower computation complexity is needed. So this method is a good choice for onboard GMTI processing for airborne fire-control radar. |
