摘要:
毫米波Costas调频步进(Chirp-Step)编码雷达是一种距离高分辨率雷达，实现运动目标的距离高分辨必须进行运动补偿。本文采用脉冲多普勒测速的运动补偿方法，并对其在不同速度下，对高速运动目标的补偿进行了仿真分析。结果表明该方法补偿精度高，运算速度快。用该方法速度补偿后，可以得到运动目标的高分辨一维距离像。
Millimeter wave (MMW) Chirp-Step Costas coded radar is a high-resolution distance radar, and motion compensation has to be implemented to improve resolution of moving target. This paper adopts an approach for motion compensation based on Pulse-Doppler velocity, and analyzes the effect of compensation for high velocity target with diversified velocity. The simulation result con-firms effective and fast effect of the technology. High resolution 1-D range profile is generated by using the algorithm.
