摘　　要：平台运动导致了机载雷达主杂波的多普勒频移和展宽,因此为了更好地抑制地杂波和检测运动目标,需要对主杂波频率中心进行精确跟踪。提出了一种基于GPS和INS系统的机载雷达主杂波跟踪方法。经仿真验证该方法可精确跟踪主杂波,同时性能稳健且环境适应性强,具有较高的工程应用价值。In airborne radar,Doppler frequency shift and broadening are induecd by the platform motion. For effectively suppressing the clutter and detecting the moving target,the precise main clutter tracking is needed. A novel tracking method is proposed for airborne radar which is based on the GPS and inertial navigation system. Simulation results show that the proposed method not only has accuate performance but also owns robust and adaptive characteristic. Therefor,the novel method has higher merit for engineering application.
