Verfahren und Vorrichtung zum ortsaufgeloesten Erfassen und Rekonstruieren von Objekten mittels Mikrowellen

WO 2009065369 A1 UPAB: 20090609 NOVELTY - The method involves providing a set of microwave antenna units (1) in a spatial distribution around an object (P) to be detected, where the antenna units are arranged at a distance to each other, such that the distance is larger than wavelength of microwaves. The antenna units are selected and activated for transmitting the microwaves, and the microwaves reflected by the object are received by another set of microwave antenna units. Microwave signals are generated and stored by the latter set of antenna units, and the stored microwave signals are analyzed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for spatially resolved detection and reconstruction of objects with a set of microwave antenna units for producing microwaves. USE - Method for spatially resolved detection and reconstruction of an object e.g. packaging piece, cargo and person, during security check in airport and railway station and/or crossing of a border. ADVANTAGE - The method enables analysis of the microwave signals in an accurate manner, thus identifying the object in a graphical position and a spatial position with reduced constructional expenditure
