Abstract

In order to evaluate the viability of frequency equipment in complex electromagnetic environment, the electromagnetic radiation effect evaluation model of random noise is established based on the analysis of the blocking effect mechanism of frequency equipment. Through MATLAB calculation, the corresponding relationship table between the ratio of the critical interference field strength effective value of single frequency continuous wave and sinusoidal amplitude modulation wave and the key parameters of the model is given, and the prediction method of noise electromagnetic interference of frequency equipment is proposed. Taking a Beidou navigation receiver as the test object, the accuracy of the noise electromagnetic radiation blocking effect model is verified by single frequency continuous wave, random noise and narrowband noise electromagnetic radiation blocking effect test, and the maximum error is only 1.51 dB, which indicates that the model and prediction method proposed in this article can accurately evaluate and predict the electromagnetic radiation interference of random noise.
