Aiming at the need of multi-radar multi-view wide-band data fusion to improve imaging resolution, a data correlation and sparse component analysis method is proposed to analyze and coherently process multi-view multi-band broadband data in a small angle. The target characteristics of more viewing angles within the small angle range improve the target two-dimensional imaging quality. The simulation experiment analyzes the error of wideband data reconstruction and verifies the correctness and effectiveness of the data fusion method.
Aiming at the target characteristics and scene generation requirements of radar targets in defense system, a radar target attitude inversion method based on narrow-band radar tracking data is proposed. The measured data of the radar sensor is collected, the dynamic scene is analyzed and excavated, and the target radar line-of-sight angle inversion model is established based on the target electromagnetic scattering characteristic simulation data. Based on the model, the attitude inversion of the radar target is completed, and target dynamic RCS is used to verify the model. The correctness and effectiveness of the radar target attitude inversion method are verified.
