| 摘 要： | 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.

| Abstract: | The radar altimeter auto test system and the original test method were introduced,and the disadvantage that this method is inefficient was brought forward.The method of radar altimeter sensitivity testing using dichotomy method,which was used to improve the efficiency of radar altimeter sensitivity testing,was proposed.The test result and test flow were presented.Using this method a few stimulating and output voltage data were used to fitting the relation function,which was used to calculate the begin stimu... |
