Echo Simulation method of space micro-motion multi-target bistatic radar

Dynamic echo data is the basis for studying the detection and recognition of space micro-motion multi-target. The micro-motion multi-target echo of bistatic radar Simulation method based on the scattering center model is studied. Firstly, this method establishes the corresponding Observation coordinate System for each space micro-motion target. Then, the positions of the target scattering centers in the Observation coordinate System are solved according to the micro-motion model, and the scattering center coordinates in the Observation coordinate System are transformed into the reference coordinate System. Finally, the Variation of micro-motion ranges are solved for the echo Simulation combined with bistatic visual conditions. The result of dynamic Simulation and electromagnetic calculation Simulation validates the effectiveness of the proposed method, which can be applied in the research of space micro-motion multi-target imaging, feature extraction, and other fields. © 2024 Chinese Institute of Electronics.
