One-dimensional scattering centre extraction for efficient radar target classification

A technique is presented to extract one-dimensional scattering centres of a complex radar target. To maintain super-resolvability, estimation accuracy and robust detection of scattering centres, the model-based technique, and the FFT-based technique, are combined in an efficient manner to take advantages of both techniques. The performance of the proposed algorithm is examined through Monte-Carlo simulations and classification experiments. It is shown that the proposed technique can be employed in the feature extraction stage for efficient radar target classification.
