摘　　要：二次差频测距具有原理简单、接收机和发射机设计相对容易等优点，所以在连续波雷达测量中有着广泛的应用。对二次差频测距的基本原理进行详细推导，并研究了二次差频法下如何正确解距离模糊问题，通过仿真实验验证了该方法的有效性。Quadric difference frequency, due to its advantages such as simple principle and easy design of receiver and transmitter, is widely used in CW radar. The principle of ranging based on quadric difference frequency is deduced in detail, and the problem how to solve range ambiguity correctly is analyzed. Finally, simulation results verify the validity of the method.
