Characterization of EMI effects in communication data link system in the presence of high-power radar radiation

Abstract

Effects of radar pulse interference with high power on the communication data link system on a warship platform are investigated with the help of Simulink simulation platform and in-house developed MATLAB algorithm. Based on the established model of communication data link system, FDTD simulation is at first employed for simulating the induced voltage on the wire antenna of date link system in the presence of a radar pulse radiation. The communication quality of the system is further evaluated for different interference waveforms of the incident radar pulse with high power. It is numerically shown that the transmitted information, in some cases, could not be restored at the receiver, which can provide certain guidance for evaluating complex electromagnetic environment effects on the warship platform on the local communication system.
