双源正弦波对某无线电引信的辐照效应预测方法

Prediction Method of Irradiation Effects of Dual Sine Waves on Certain Radio Fuze

以某连续波多普勒无线电引信为受试设备,在电波暗室内,分别开展了单源和双源正弦连续波对引信的电磁辐照实验。实验结果表明:在双源正弦连续波辐照下可以得到一系列引信的临界发火场强组合,场强组合并不呈现规律性,且2个正弦连续波的差频不同,其场强组合的总场强相差很大,因此不能直接通过单源正弦连续波的临界发火场强曲线对双源正弦连续波的辐照效应做预测。通过对实验结果进行对比分析,提出了双源正弦连续波的电磁辐照效应预测方法,验证结果显示该预测方法具有较高的准确性。

A continuous wave Doppler radio fuze is taken as equipment under test,a single source contin-uous sine wave and dual continuous sine waves electromagnetic irradiation experiments are conducted on fuze in EMC anechoic room.The results indicate that a series of critical firing field intensity combination are obtained under the dual sine waves’irradiation,no regularity is found from the combination,when the frequency difference of two continuous sine waves differs,the total field intensity has a big difference. Therefore,the irradiation effects of dual continuous sine waves can’t be predicted through the critical fir-ing field intensity curve of the single sine continuous wave.Through comparison and analysis of the ex-perimental results,it puts forward a method to predicate the electromagnetic irradiation effects of dual sine continuous waves.The experiment indicates the prediction method has a reliable accuracy.
