Abstract
This paper introduces and analyses the performance of different techniques to estimate the parameters of ground moving targets in multi-channel SAR data. Candidates are filter-banks, the interferometric phase and direction-of-arrival estimation methods, which can work in either the raw data or the compressed SAR image domain. Of particular interest are systems with only two channels because many existing or near-future SAR systems, such as RADARSAT-2, are restricted to a maximum of two sub-apertures. Desired parameters are the two velocity components (along- and across-track) and the true location. The results are evaluated with experimental airborne SAR data.
