Target Recognition Based on Attributed Scattering Center Models

In order to extract the target's geometric electromagnetic characteristics effectively from the radar echo, this paper proposes a fast feature parameter extraction method of attributed scattering center model. We use the orthogonal matching pursuit (OMP) algorithm to estimate the attributed scattering center model. In the process of OMP algorithm, the RELAX algorithm is used to correct the extracted signal components. Compared with the traditional super-resolution algorithm based on point-scattering model, this algorithm can effectively solve the problem of discontinuity of components. And it is more accurate to describe the geometric features and position of the target.
