A new algorithm based on dual frequency is proposed in this paper for multiple frequency CW radarranging.
本文提出一种基于双频测距的多频连续滤雷达测距新算法，即二次相差法。

In the experiment, we build the laser diode radarranging system, and use of the devices under different conditions of a large number of fixed-point ranging experiments.
在实验上，搭建了测距型激光二极管雷达的实验装置，并利用该装置进行了不同条件下的大量定点测距实验。

The results show that:in the low SNR conditions, the discrete distribution of the laser diode radarranging data will significantly deviate from the normal distribution;
