ABSTRACT:
A method is disclosed of generating multi-resolution images using synthetic aperture radar (SAR) phase history data. A high resolution SAR image may be formed from the phase history data, or a lower resolution SAR image may be formed from a sub-aperture of the phase history data. The multi-resolution images may also be compressed. Compressed multi-resolution images are progressively transmitted to a client until the client receives an image with adequate image quality and/or resolution. Compressed multi-resolution images may also be used for iterative target detection, where images are analyzed by a target detection processor, starting with a lowest resolution image, going to a highest resolution image, until an adequate image of the target or scene is obtained. If a target is not found in the multi-resolution images, a new sub-aperture is chosen on the phase history data, and the target detection process repeats for the new sub-aperture.
