Abstract:

Aiming at the deficiency of the frequency equipment radiation susceptibility test in the complex electromagnetic environment, the prediction method of the in-band dual-frequency continuous wave electromagnetic radiation effect is studied. The in-band dual-frequency electromagnetic radiation effect prediction model is established based on interference mechanism and coupling mechanism of the frequency equipment, and the electromagnetic radiation effect test scheme is designed with a VHF radio as the test object. The communication equipment electromagnetic radiation effect test is carried out with single frequency and double frequency, the electromagnetic radiation susceptibility regular pattern under the combined action of the in-band dual frequency different weights is discussed. Experimental results show that the prediction model coefficients of the dual frequency continuous wave electromagnetic radiation effect are about 1 in different frequency combinations and different power intensities, and the prediction error is within ±1dB. The validity of the model to forecast the in-band dual-frequency continuous wave electromagnetic radiation effect is verified finally.
