The Neyman-Pearson lemma, i.e., the likelihood ratio test and its generalized version, have been used for the development of the synthetic aperture radar (SAR) change detection methods. For detecting changes caused by targets on the ground such as ve

Image coregistration is a mandatory procedure for radar applications such as synthetic aperture radar change detection. The spatial coregistration can be easily handled with geo-reference, whereas radiometric coregistration requires much more effort

Conventional SAR refers to systems with small fractional bandwidth and short relative aperture whereas non-conventional SAR refers to systems with large fractional bandwidth and long relative aperture. The change detection methods developed for non-c

The pursuit monostatic is a SAR operating mode that requires two SAR data acquisitions separated in short time (seconds) using the same flight tracks and being. In this case, the changes in a SAR scene come mainly from ground moving targets, thus ope

Synthetic-aperture radar (SAR) is normally used in an active mode for ground surveillance. Passive SAR has also been demonstrated using DVB-T (Digital Video Broadcasting – Terrestrial) signals from TV-broadcasting masts as illuminators of opportuni

This paper presents the moving target focusing method, which allows focusing moving targets in complex synthetic aperture radar (SAR) images without raw data. The method is developed on the range migration algorithm, where focusing moving target is a

Synthetic aperture radar (SAR) gives not only the opportunity to image targets with high resolution but also to measure their position and velocity. Without acceleration (constant speed), the position and velocity both in range and azimuth can be est

Stand-alone synthetic aperture radar (SAR) ground moving target indication (GMTI) methods have both advantages and disadvantages. This paper introduces a hybrid SAR GMTI method that is based on two well-known methods: space time adaptive processing (
