A Parameter Extraction Method for Cone-shaped Space Targets Based on Scattering Center Model

This paper proposes a parameter extraction method, which can extract structure parameters and micro-motion parameters for cone-shaped space targets based on scattering center model. This method is divided into two parts: obtaining the time-varying scattering center model and extracting parameters. Firstly, the time-varying scattering center model for group targets are extracted from the high-resolution range profiles by the least squares method and Kalman filters. Secondly, the time-varying SC model are decomposed and analyzed to obtain the scattering features for isolated targets. Finally, the intrinsic parameters of cone-shaped space targets are extracted by deep learning from multiple scattering features and physical features. Simulations validate the effectiveness of the proposed method.
