线性调频连续波体制汽车防撞雷达目标特性研究

Target characteristics of LFMCW automobile collision avoidance radar

根据调频连续波体制雷达的工作原理,以及道路上目标的运动类型,建立基本的道路目标信号数学模型。对实际回波可能存在的杂波和噪声进行分析,加上目标信号,合成最终的回波信号,并用MATLAB进行仿真,以期为汽车防撞雷达目标模拟器的研制提供参考。

A basic mathematical model of road target signal was set up based on the principle of the LFMCW radar and the type of motion on the road. The possible clutter and noise of the actual echo were analyzed. The final echo signal was synthe- sized by adding the target signal and simulated by MATLAB, so as to provide a reference for the development of the target simulator for the collision avoidance radar.
