摘要

针对复杂电磁环境下用频装备战场生存能力研究的不足

对某型通信装备在带内多频电磁环境下的生存能力进行了研究。通过对通信装备带内干扰效应原理分析

分别从不同的敏感参数角度出发

建立了2种通信装备带内多频电磁环境生存能力预测模型;并通过某型通信装备带内单频、双频、三频连续波电磁辐射效应试验

研究了受试装备在不同频率组合、不同强度组合下电磁辐射效应的变化规律。试验结果表明:受试装备的带内双频、三频电磁辐射效应试验的验证结果（即平均功率比值之和）基本都在1上下浮动

与平均功率敏感的模型十分相符;电场强度幅值敏感模型的验证结果（即电场强度幅值比值之和）双频电磁辐射为1.4左右

而三频达到了1.6。因此

受试装备带内电磁效应由干扰信号平均功率决定

第2种预测模型能够有效预测带内多频电磁环境下通信装备生存能力。

Abstract

In order to improve the survivability of the frequency equipment

we analyzed the survivability under the in-band multi-frequency electromagnetic environment of typical communication equipment. To analyze the in-band interference mechanism

we established two survivability forecasting models based on two different susceptibility parameters. The electromagnetic radiation effects of single-frequency

dual-frequency

and triple-frequency continuous wave in-band were tested

and the radiation effect change rule was studied in the different frequencies and different magnitudes combinations. The results show that the average power determined model results of in-band dual-frequency

and triple-frequency tests are all approximate 1

the amplitude determined model results are different

the dual-frequency tests results are about 1.4

and the tri-frequency tests results are about 1.6. The results demonstrate the electromagnetic radiation effect in-band of the equipment under test is determined by the interference signal average power

and the second model is able to forecast the typical communication equipment survivability effectively under the in-band multi-frequency electromagnetic environment.
