Post processing techniques for inverse synthetic aperture radar imaging

Inverse Synthetic Aperture Radar (ISAR) is generally used for classification of ship targets after detection and tracking by the Radar. There are various methods for high resolution 2D imaging of maritime targets in ISAR mode like Range Doppler Algorithm and Polar Format Algorithm. After the raw image is formed, it has to pass through the post processing algorithm suite before an acceptable image can be displayed to observer. This paper presents an efficient algorithm suite for the post processing of ISAR image.
