A method for the production of a moving objects in the microwave range image taking place by means of inverse - - - synthetic aperture radar

摘要

to produce a figure of moving objects in mikrowellenbereich held by inverse - synthetic aperture raders (isar), the two-dimensional ortsverteilung the ru00fcckstreuzentren of each object is determined, particularly for monitoring the bodenverkehrs on flughu00e4f s, based on a variety of entfernungszellen is providedthe suppression of because of dopplerverschiebungen resulting disturbance in the form of pixels formed mikrowellenabbildungen only those pixels as a intensitu00e4tsschwellenwert actively at the crossing, the first fixed fraction of the maximum... iegenden pixelintensitu00e4t has been determined.there will also be a disturbed distance range with the help of a schwellwertu00fcbertragungsmethode under counting of the number of active pixels for each successive entfernungszellen determined and identified a bildu00f6ffnung disturbed distance range is carried out in a the sequence of one or more recurrent erosions and dilatations iswith an erosion formed is that all those active pixels are deleted in the defined neighborhood an inactive pixel is found, and a dilation is that in an active pixel, all pixels of the specified neighborhood to be activated.
