A Pole Extraction Algorithm Based on Sliding Windowed Matrix Pencil Method

This paper proposes a pole extraction algorithm for robust radar target recognition based on Sliding Windowed Matrix Pencil Method (SW-MPM). The time domain scattering data of the target are windowed and the poles are extracted by Matrix Pencil Method (MPM) with a sliding window. The number of poles parameter is changed to improve the reliability of poles extraction, and the azimuth consistency of poles extracted from multiple azimuths is analyzed. We simulate and verify the effectiveness of the pole extraction method under different directions of the aircraft target.
