In the experiment, we build the laser diode radar ranging 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 radar ranging data will significantly deviate from the normal distribution;

研究结果表明：在低信噪比条件下，激光二极管雷达测距数据的离散分布将明显偏离正态分布；

Based on inputs ranging from radar data and current position to mission status and intelligence feeds, the system would divide the set of all possible actions into those that are ethical and those that are not.
