阐述了雷达高度表自动测试系统软硬件组成和原雷达高度表告警信号测试方法,指出原测试方法存在的测试效率低下问题,针对该问题提出了基于最小二乘数据拟合的雷达高度表告警信号测试方法,并给出了测试数据和实验结果.该测试方法首先应用少数激励和输出数据进行数据拟合,应用拟合函数确定发出告警信号的激励电压初始电压值,再以小电压幅度逐次调整激励电压,以完成精确测量,应用该方法可在保证测试精度的前提下大大提高测试效率.
The hardware and software composition of radar altimeter automatic test system and the test method of the original radar altimeter alarm signal are expounded. The problem of low test efficiency of the original test method is pointed out. A radar altimeter alarm signal based on the least square data fitting The test method is given and the test data and experimental results are given.The test method first applies a few excitation and output data for data fitting and applies the fitting function to determine the initial voltage value of the excitation voltage for issuing the alarm signal and then adjusts the voltage value successively Incentive voltage to complete the precise measurement, the application of this method can greatly improve the test efficiency under the premise of ensuring the accuracy of the test.
