微波测距仪测距精度误差因素的影响分析

微波测距仪测距过程中,影响测距精度的因素较多,有大气介质（湿度、温度、大气压等）、零点误差、偏移值、测相误差、计数时钟频率漂移误差等,这些因素对测距精度的影响各不相同。本文以某型微波测距仪为例,分析各主要因素对测距精度的影响程度,同时,结合实际经验,给出确保测距精度的方法。

Error factors impact analysis of microwave rangefinder ranging accuracy

In the ranging process of the microwave rangefinder,many factors can affect the accuracy of distance measurement.they are atmospheric medium(humidity,temperature,atmospheric pressure,etc.),zero error,offset value,error of measured phase,error of frequency drift of count clock,and so on.These impact of the factors on the measurement accuracy varies.In this article,there will be an analysis of influence degree of the factors on the measurement accuracy.At the same time,it gives a way to ensure the measurement...
