    • The invention relates to a method for processing imaging radar data of distributed and/or multiple layover scatterers contained in one or more preselected radar resolution cells, acquired by a radar system having at least one receiving channel with multi-pass multibaseline acquisition and consisting of at least one set of complex valued pixels. Each set corresponds substantially to a respective resolution cell in a plurality of complex focalized radar images, and each radar image is formed through each receiving channel for each pass. The method according to the invention comprises a multidimensional separation step, in particular two-dimensional, in a domain comprising the height/displacement velocity joint domain, of multiple radio echo components coming from the distributed and/or multiple layover scatterers in said or each cell, where the separation is carried out by means of two-dimensional processing step of the data in the baseline/acquisition time joint domain, said separation comprising the extraction in the height/displacement velocity joint domain of data of a distribution on height and displacement velocity of said scatterers and/or of components of said distributed and/or multiple scatterers. This method allows forming a differential tomographic image (70) that describes the reconstructed radio reflectivity (71) vs. height (72) and the displacement velocity (73), for three layover isolated scatterers from which three dominant reflectivity peaks depend (74,75 and 76), with a maximum ambiguities level (77) that is satisfactorily low.

    • A method of processing a temporal sequence of base images from a synthetic aperture system such as a synthetic aperture radar is provided that simplifies the task of identifying moving objects. The method comprises the steps of firstly temporally filtering a plurality of the base images to form a reference image, and secondly normalising the reference image with a base image to form a change detection image. The change detection image has the property that all moving objects are emphasised. Further processing can optionally be performed on the change detection image to remove false targets based on characteristics of the highlighted areas or on a temporal track taken over a plurality of change detection images. The invention allows detection of moving objects without requiring a Doppler return from a target. The invention extends to a system adapted to implement the method, and a computer program.
