Azimuth Displacement Indicator - a Multichannel SAR Technique for Moving Target Detection and Estimation

Inhalt:
An alternative to the classical Displaced Phase Center Antenna (DPCA) and Along Track Interferometry (ATI) techniques is described for SAR processing of moving targets. It is implemented through a pre-focus and a post-focus multiplication with no need for channel co-registration. This technique is easily extendable from a dual-aperture to multi-aperture systems. Analytical derivations, presented herein, complement our previous experimental results.
