摘　　要：介绍了二次相差法测距的基本原理,并对二次相差法多频连续波测距体制在分离多目标的问题上进行了研究分析。通过对二次相差法测距性能进行了仿真分析,仿真结果表明,基于双频比相测距的二次相差法多篇连续波雷达,只能求解速度不同的目标的距离值,无法求解同速度不同距离目标的距离值。This paper describes the principle of ranging based on quadric phase difference in details,then simulates the performance of ranging based on quadratic phase difference and provides an analysis of the simulation,and finally gives a study on the problem of the multiple frequency CW ranging radar based on quadratic phase difference in dealing with multiple targets.Simulation results show that the quadratic phase difference-based multiple frequency CW ranging radar can only resolve the ranges of targets at different speeds,but not the ranges of different targets at the same speed.
