Electronic reconnaissance system has complex structure, high research cost and long research cycle, so it needs to rely on realistic and practical simulation system to help test and evaluate. The functional level simulation system relies on the artificial setting of parameters, which can not reflect the whole signal processing. The signal level simulation system can truly reflect details of the whole process of generation, transmission and processing of zero intermediate frequency signal in the system. It is rich in detail information, but has the prominent problems of slow simulation speed and large memory consumption. Therefore, the signal level simulation has high requirements for computer performance, which is difficult for ordinary computers to meet. To address the problems of insufficient details of functional level simulation and high computer performance requirements of signal level simulation in large-scale simulation scenarios, this paper designs a hybrid simulation scheme for electronic reconnaissance systems by integrating functional-level simulation and signal-level simulation. By comparing, selecting and correlating multiple granularity simulation models, a hybrid electronic reconnaissance simulation system was finally built to achieve a balance between simulation speed and simulation fidelity.
