现在通用的天线转速测试法不能得到瞵时变化的数据.本文介绍了一种采样率较高的短时平均速度测试法,它是一种准瞵时测量法.利用 MIC—85单板机,时间量化单元为5μs,最短采样间隔约80μs,最长采样间隔为65ms,可连续测量16圈,存储4096个致据,并可打印出所测数据及其编号,计算并打印出每圈实际速度、瞵时误差及均方差.本文还介绍了某种雷达上测试瞵时速度而不需对雷达进行任何改装的方法,(?)为例子,给出了一(?)测试的曲线.
Now the common method of antenna rotation speed test can not get the data of the time variation.This paper introduces a high sampling rate of short-term average speed test method, which is a quasi-time measurement method.Using the MIC-85 single-board machine, Time quantization unit 5μs, the shortest sampling interval of about 80μs, the longest sampling interval of 65ms, continuous measurement of 16 laps, store 4096 to the evidence, and can print out the measured data and its number, calculate and print the actual speed per lap , 瞵 hour error and mean square error.This paper also introduces a method of testing the speed of a radar without any modifications to the radar, (?) As an example, gives a curve of a test.
