| Abstract: | Convolution back projection (CBP) algorithm for inverse synthetic aperture radar (ISAR) imaging is studied in this paper. An improved CBP algorithm is proposed, by which the whole interpolation work can be completed in a single one-dimensional (1-D) shifted interpolation. Based on this, a large scene can be divided into small scenes and processed in parallel. From the ISAR images using FEKO simulated data, it is demonstrated that the improved CBP algorithm is far more efficient than the conventional method. |
