摘要/Abstract

摘要： 当电台处于外界复杂电磁环境中，会有多种频率的干扰信号同时作用，如果信号强度足够，即便落于带外也有可能造成电台阻塞，使其接收不到有用信号而失去作战效能.带外信号造成接收机阻塞所需的能量高，利用矢量法将有用信号和干扰信号进行矢量叠加，通过推导得到相应的干扰预测模型.利用两套独立的干扰发射系统进行双频干扰试验，试验前要对试验系统进行调整，之后再分别以误码率0.1和受试电台接收不到链路测试作为临界干扰判别标准进行两次试验，试验结果表明以上模型能够预测受试设备是否达到临界干扰状态，预测误差在2dB以内，同时以上两种临界干扰标准均适用.

Abstract: The communication station will be affected by interference signals of multiple frequency in complex electromagnetic environment.Assuming the interference signal is strong enough,the communication station will be blocked even if the interference signal is out of band,which makes it unable to receive useful signal and lose combat effectiveness.The out-of-band signal needs significant energy to block receiver;so we can use vector superposition method to analyze useful signal and interference signal,from which the interference prediction model can be derived.Conducting dual-frequency interference test by two independent interference transmission system,and the system should be adjusted before the test.Taking error rate to be 0.1 and no link test as the critical interference criterion respectively,and then two independent tests are conducted.The test result shows that the presented model is able to predict whether or not the equipment under test reaches critical interference state,and the prediction error is within 2dB.This model applies to both critical interference criteria.

Key words: communication station, out-of-band interference, blocking effect, modeling
