Abstract:The complex electromagnetic environment effects on radar system is a hot topic at present. Based on the analysis of the complex electromagnetic environment for radar, the representation method of electromagnetic environment elements is studied, and the quantization index of electromagnetic environment effect on radar signal and data processing is put forward. Then, the signal model of radar electromagnetic environment and the radar signal receiving and processing, data processing model are established. The simulation method of radar electromagnetic environment effect is given, which supports the parameterized input of different complex electromagnetic environment elements. Dynamic simulation of the interaction between complex electromagnetic environment and radar system is realized, and the transient and statistical features of each node can be obtained. The preliminary results verify the correctness of the research ideas, which can provide a large sample data support for establishing the mapping relationship between the elements of complex electromagnetic environment and the effect of complex electromagnetic environment.
