Modified MEMP Method for 2D Scattering Center Measurement Based on GTD Model

摘要：

To accurately measure scattering centers of the stealthy object whose main scattering centers are formed by the edge diffraction,a modified matrix enhancement and matrix pencil (modified MEMP) method is utilized based on the geometric theory of diffraction (GTD) model. Traditional MEMP method needs plenty of eigenvalue decomposition computation and an additional pairing step. When two or more distance parameters are equal or close,the MEMP may produce incorrect paired results. The modified MEMP method can avoid these drawbacks. Simulations show it is accurate and has a good resolution; moreover,this method can estimate the types of scatterers.
