摘　　要：本文介绍了一种适用于舰船航行速度测试的微波多普勒雷达方案。本方案采用连续波发射,零中频接收,使得组件前端电路简易,信号处理简单,并且采用IQ正交双通道接收机方式保留了目标运动方向信息。另外,利用加速度测量芯片跟踪舰船由于海浪起伏引起的天线角度变化,从而可以精确测量舰船的即时水平行进速度。This paper introduces a program of microwave Doppler radar for Vessel Velocity Measurement.The program uses a continuous wave emission,zero-IF receiver,making front-end circuits easy and signal processing simple.Moverover, the program uses IQ orthogonal two-channel receiver to obtain the velocity and direction,and track the antenna angle caused by wave using acceleration measurement chip,leading to calculate the real-time speed of vessel moving real-time speed accurately.
