复杂射频电磁环境下,无线接收机作为主要的敏感设备,其电磁兼容性直接影响着整个武器装备的电磁兼容特性. 本文针对GJB 151B中对于接收机非线性测试方法的局限性,引入了一种利用自动双频测试系统对接收机干扰响应的快速测试方法;并搭建了实验室半实物仿真测试平台,检测了某接收机在( 4~6 ) GHz组合频率干扰下的所有非线性的干扰响应通道. 测试结果对于评估接收机及其所在系统的外部电磁环境适应性具有重要参考价值.

Wireless receiver's EMC characteristic influences directly that of the entire weapon sys-tem while it is the most sensitive equipment in the complicated RF electromagnetic environment ( EME) . In consideration of the limits of the testing methods for receiver's nonlinear characteristic given by GJB 151B, this paper presents a fast interference response testing technique based on the automated double frequency system. Experimental testing and analysis of receiver is performed here as an application exam-ple, which includes the detection and recognition of all the nonlinear interference response under scan-ning frequency (4~6) GHz. Testing results are pretty valuable for the estimation of the actual environ-ment adaptation of the receiver and system in severe EME.
