机载无线电设备兼容性内场试验方法

机载无线电设备之间的兼容性试验是飞机研制完成之后进行的一项重要整机性能试验项目，当前主要通过外场飞行来完成。提出了一种新的试验方法，即采用内场辐射式试验方案来完成无线电设备装机之后的兼容性试验。首先以典型机载无线电设备为基础，分析整机内场兼容性试验需要完成的试验项目，进而阐述内场辐射式试验系统的总体方案。该方法具有以下特点：易于构建复杂电磁环境；可完成机载无线电设备之间的兼容性试验；可完成整机在复杂电磁环境下的工作性能评估试验。这些工作在促进航空工业的发展、提升国产新型飞机的技术水平及市场竞争力等方面具有重大工程应用价值。

Indoor compatibility test method for airborne radio equipment

Compatibility test for airborne radio installations is one of the important items for whole aircraft performance test after the aircraft is developed. A new test method called indoor radiation test scheme is proposed to complete the compatibility test by replacing parts of the outdoor flight test items. The test items needed to finish are analyzed on the basis of the typical airborne radio equipment. Then the general solu-tion for the indoor radiation test is described. With this indoor test method,complex electromagnetic envi-ronment can be built easily,the compatibility test between airborne radio equipment and performance evalu-ation test of the whole aircraft in complex electromagnetic environment can also be implemented. The work has significant engineering application value for promoting the development of aviation industry and enhan-cing the technical level and market competitiveness of new types of domestic aircraft.
