| 摘 要： | 超高速运动目标是现代雷达目标检测中遇到的新情况。文中建立了超高速运动目标的回波模型，得出其信号模型是一多项式调频信号。根据超高速运动目标回波信号的特点，给出了先进行多普勒处理再进行脉冲压缩的超高速运动目标检测方法。分析了目标的超高速运动对雷达目标检测的影响，并对理论分析进行了仿真验证。最后给出了问题的解决方向。

| Abstract: | Ultra-high speed moving target is a new case for radar target detection.The echo model of the moving target is established in this paper,and it is shown that the return signal of the target is a polynomial frequency modulated signal actually.A new method in which Doppler processing was done before the pulse compression was put forward basing on the characteristics of the ultra-high speed moving target's return signal.Then we analyzed the influence of the ultra-high speed moving of the target on radar detection.The validity of the theoretical analysis was proved by simulation.At last,we show a way to solve this problem. |
