基于通用仪器的机载气象雷达测试平台的实现

Implementation of airborne weather radar test bench based on general instruments

RD-301A作为气象雷达测试仪被应用于××型机载气象雷达。但随着机载雷达产品的不断更新换代,RD-301A的测试功能已无法满足现代航空电子产品的测试需要。针对这种现状,利用通用仪器组成测试平台,对××型机载气象雷达进行功能指标对比测试。试验结果表明,利用通用仪器组成的测试平台可以完成××型机载气象雷达指标测试,可以在功能上初步替代RD-301A航电测试仪。

As time goes on, the radar productions are updated over time. The needs of the modern avionic production testing cannot be satisfied by the RD-301A test set. In this paper,a test bench is established, which comprises some general instruments. The functions and parameters of an airborne weather radar are tested using the test bench in contrast to RD-301A. According to the results of the experiment,the RD-301A test set can be replaced by the test bench built by general instruments in functionality testing of the airborne weather radar primarily.
