Digital geographic information based complex electromagnetic environment signal simulation and generation

The semi-physical simulation test method is the research focus of electronic warfare equipment performance evaluation test in complex electromagnetic environment. The complex electromagnetic environment signal generation technology based on digital geographic information is an effective technical approach to implement semi-physical simulation test. In this paper, the idea, method and current development of this technology was introduced from three aspects, i.e. simulation modeling in complex electromagnetic environment, electromagnetic signal propagation simulation based on digital geographic information, and complex-type signal generation.
