摘要
针对通信对抗系统中超外差接收机的建模仿真问题,以Matlab中的Simulink软件包作为工具建立基于Simulink仿真平台的超外差接收机的仿真模型,给出频率为5kHz的调幅信号的动态仿真实例,并得到各关健点的仿真波形图和频域图,实验结果证明了该建模方法的有效性。
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.
