| 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。建立了超高速运动目标的回波模型，分析了其对目标检测中脉冲多普勒处理的影响，并提出了基于匹配傅立叶变换的脉冲多普勒处理方法。针对回波模型的特点，提出了一种计算量较小、物理含义清晰、搜索范围针对性强的超高速运动目标检测的实现算法，并对理论分析进行了仿真验证。

| Abstract: | Ultra-high speed moving target is a new case fallen across in modern radar target detection. An echo model of ultra-high speed moving target was established, and its effect on pulse Doppler pro?cessing was analyzed. A pulse Doppler processing method based on matched Fourier transform (MFT) was proposed. According to the characteristics of echo model, an algorithm was proposed to realize MFT-based ultra-hign speed moving target detection with light computation load, clear physical mean?ing and strong searching range pertinence. The simulation results show the validity of the algorithm. |
