Abstract: Aiming at the problem of modeling and simulation of superheterodyne receiver in communication Electronic Warfare(EW) system, this paper utilizes Simulink of software bundle in Matlab to construct simulation model of superheterodyne receiver based on Simulink platform. Dynamic simulation example of the amplitude modulation signal with the frequency of 5 kHz is given, and simulation waveforms and frequency chart are given. Experimental results show that the modeling method is effective.
