摘要
随着各类电子设备的大量应用,现代战场电磁环境日趋复杂.为研究复杂电磁环境下用频装备随机噪声辐射效应评估方法,设计了超短波通信电台噪声辐照干扰实验.以应用机理分析建模和实验数据统计分析验证为理论依据,综合考虑装备在噪声干扰下的辐射敏感度变化规律,提出了噪声辐射下通信电台电磁干扰的评估模型.将实验数据带入预测模型求得参数值,将其与理想值进行比较,若干扰系数S大于1,则通信电台有可能受到干扰;若S小于1,则通信电台一定不会受到干扰.
Abstract
With the extensive use of different kinds of electronic equipment,modern battlefield electromagnetic environment is becoming more and more complex.The noise radiated interference experiment of a certain VHF radio station is designed in order to study the interference effect caused by random noise on equipment using frequency in complex electromagnetic environment.The authors take the mechanism of application analysis modeling and analysis of the data from experiment as the theoretical basis,consider the laws of equipment 's sensitivity variation under the noise interference, and propose the evaluation model of the radiated noise on the radio electromagnetic interference.It is found that if the interference coefficient S is greater than 1,the communication station may be interfered;but if the S is less than 1,the communication station will not be disturbed.
