Method of classifying and identifying an object using Doppler radar

Abstract

The invention relates to a method of classifying and identifying an object, for example satellites, aircraft, land vehicles and ships with a Doppler radar system in which a video signal is generated by means of coherent signal processing and tracking data including, position and changes in position, are determined from the video signal for the object. The method includes representing the object as an inverse synthetic radar aperture image and then selecting a reference object with the aid of the tracking data and the rotational axis of the object. A representation of the reference object is rotated into a position that corresponds to the spatial rotational axis of the object and then superimposed over the inverse synthetic aperture radar image of the object. Identification of the object is effected by comparing the representation of the rotated reference object with the inverse synthetic aperture radar image.
