Interpolated Spatially Variant Apodization in Synthetic Aperture Radar Imagery
Abstract
The original formulation of spatially variant apodization for complex synthetic aperture radar imagery concentrated on integer-oversampled data. Noninteger-oversampled data presented previously IEEE Trans. Aerosp. Electron. Syst. 31, 267 (1995) suggested use of different weightings in the algorithm. An alternative noninteger-oversampled approach that employs the same apodization concept but uses local spatial interpolation is presented. With this approach the combined image formation, apodization, and detection of 1.3 -versus-2.0 oversampled data can be performed in half the time without loss of image quality.
