摘　　要：目前使用的驼峰测速雷达一般安装在轨旁,应用多普勒原理对溜放车组的速度进行测量,一部雷达只能测量一个股道的溜放车组速度。现基于逆合成孔径雷达测速原理,提出将雷达侧向安装在溜放线路一侧的上方,并建立了雷达回波数学模型,采用了一种基于自聚焦的溜放车组速度估计算法。仿真结果表明:该算法能够精确地连续测量多股道溜放车组的瞬时速度。Nowadays hump velocity radar is usually installed at trackside,using Doppler principle to measure truck velocity,one radar can only measure one track speed. So,based on principle of inverse synthetic aperture radar velocity measurement,radar is installed above truck line on one side,and mathematic model of radar echo is set up,and velocity estimation algorithm of self-focusing for rolling set of car is used. Simulation results show that the algorithm can accurately and continuously measure instantaneous speed of multi-lanes rolling set of car.
