Coherent synthetic aperture radar (SAR) pair formation

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
The interference between two radar images, acquired from approximately the same location, has a number of uses. In particular, the literature abounds with examples of coherent change detection (CCD) and interferometric SAR (InSAR) uses which respectively enable the detection of small changes and the extraction of terrain elevation.

Real-Time Optical Synthetic Aperture Radar (SAR) Processor

Optical Engineering, 1982
A description is given of a real-time optical synthetic aperture radar (SAR). The processor employs an acoustooptic device as the input electronic-to-optical transducer and a CCD camera that serves as the optical detector and simultaneously performs the focusing of the SAR image in the azimuth direction.

Automatic registration of synthetic aperture radar (SAR) images

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
The huge amount of incoming synthetic aperture radar (SAR) data nowadays demands the need for automatic image registration. Due the presence of speckle noise and the huge size of SAR images, registering SAR images is more difficult than traditional image registration methods. In this paper we present an automatic hierarchical registration method, based

Transform coding of synthetic aperture radar (SAR) images

ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Transform Coding is a type of source coding that is used to compress the data required for images without substantial loss of fidelity. Transform Coding has been studied by many authors for optical images and the results have shown favorable compression ratios on the order of 10 to 1 without noticeable loss of picture quality. This is due to the highly
