摘要
介绍了一种简单易行的激光测距能力检测方法。该方法是根据测距方程 ,结合外场已知目标和气象条件 ,使目标的探测功率与设备要求的最小探测功率相等 ,由此求出对应的接收面积 ,用此面积对已知目标进行测距 ,当测距回波率满足要求时 ,确定设备的测距能力达到要求 。
The sensitivity of laser distance measuring instrument is studied,and an easy-operation distance ability detection method is introduced.This method is designed based on the range equation and light extinction principle.Using the pre-known objects and meteorological condition, changing the optical receiving area,and making the detection power equal to the minim detection power, the minimum receiving area is derived. Using this receiving area, an given ob ject is detected, and the distance ranging ability is regarded as meeting the challenge if the detection arability is larger than 95%.This method is used in practice,and the results are verified by the long distance objects, which shows that this method is good and practical.
