摘　　要：为解决现有机车测速仪的不足,研发一种基于非对称发射角度的双天线雷达测速仪。该测速仪由双雷达微波模块、信号调理模块、数据处理模块和电源模块组成。双雷达微波模块与地面分别构成不同的发射角,以不同的频率发射雷达波,根据能量和频谱特征接收各自发射的雷达波产生的反射波,将其传入信号调理模块分别处理后,再输入数据处理模块利用多普勒效应相关算法分别进行分析解算。模拟测试结果表明,该测速仪具有测速精度高、系统稳定、数据可靠等优点。To solve the shortcomings of locomotive velocimeter, the dual antenna radar velocimeter based on asymmetric emission angle is developed, which is composed of dual radar microwave module, signal conditioning module, data processing module and power module. The dual radar microwave module and the ground form different emission angles and transmit radar waves at different frequencies, the reflected waves are received according to their respective energy and spectrum characteristics, finally the wave singles are analyzed and calculated by using Doppler effect before signal conditioning module processing. The test results show that the dual antenna radar velocimeter is with high precision, stable system and reliability characteristics.
