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。
Taking a continuous wave Doppler radio fuze as the tested equipment, single-source and dual-source sinusoidal continuous-wave electromagnetic fuze experiments were carried out in anechoic chamber respectively. The experimental results show that a series of critical ignition field combinations of fuze can be obtained under the irradiation of two sources of sinusoidal continuous wave. The combination of field strength does not show regularity, and the difference of two sinusoidal continuous waves is different. Therefore, it is impossible to directly predict the irradiation effect of the dual-source sinusoidal continuous wave through the critical firing field curve of single-source sinusoidal continuous wave. Through the comparative analysis of experimental results, a dual-source sinusoidal continuous wave electromagnetic radiation effect prediction method is proposed, and the verification results show that the prediction method has high accuracy.
