摘要： Described herein is a method for processing SAR images generated by successive acquisitions, wherein the interferometric phase (Φ) includes at least one first contribution that represents the information of terrain height, and at least one second contribution that represents the variation of height with respect to the time that elapses between two successive interferometric acquisitions, as well as other contributions that represent the artefacts due to atmospheric inhomogeneities, to the limited precision with which the orbital parameters of the successive acquisitions are known, and to the phase variation depending upon processing errors. The method envisages linearization of the models used to estimate each of the contributions mentioned above.

摘要： 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.

摘要： A system (400) includes at least one sensor device (410) configured to transmit a first detection signal over a first spatial region and a second detection signal over a second spatial region. The second region has a first sub-region in common with the first region. The system further includes a processing device (420) configured to assign a first occupancy value to a first cell in an evidence grid. The first cell represents the first sub-region, and the first occupancy value characterizes whether an object has been detected by the first detection signal as being present in the first sub-region. The processing device (420) is further configured to calculate, based on the first and second detection signals, the probability that the first occupancy value accurately characterizes the presence of the object in the first sub-region, and generate a data representation of the first sub-region based on the probability calculation.

摘要： The invention relates to an arrangement for the interferometric radar measurement according to the ROSAR principle and to a device using said principle. The inventive device comprises two coherent reception antennae having two reception channels. The distance in the path between the two distances of the antennae and the measured points of impact is calculated by the wavelength μ of the emitted radar signal and the measured phase difference of the receiving echo of the two coherent reception channels. According to the invention, the interferometric ROSAR arrangement is integrated in or on a rotating device and positioned in such a way that the entire area to be measured can be detected.

摘要： A family of multiple scale adaptive filters (20) and filtering methods (20) that automatically adapt their impulse response width to local data characteristics, optimizing the accuracy, yield, and/or detail of interferometric measurements. A prefilter (10) with fixed impulse response width is applied to a complex interferogram. The phase of the prefiltered complex interferogram is unwrapped (25). Then, a weighted combination of the phase-unwrapped, fixed-filtered interferograms is computed (30) using a data-dependent criterion function. The resulting weighting function at each resolution element is typically a nonlinear function of interferogram magnitude and coherence for each fixed filter ouput at that resolution element.
