Abstract:
A method of analyzing the radar cross section of a target wherein the contributions to total radar cross section of various target details are determined, the method comprising:obtaining a multiplicity of ISAR images of the target by means of a radar positioned at known elevation angles and distances relative to the target as the target moves in a controlled fashion;creating a three-dimensional, visually perceptible set of images of the target as the target moves;processing the visually perceptible set of images so that the visually perceptible set of images has the same point of view as the ISAR images and each image of the visually perceptible set matches a corresponding ISAR image in terms of distance from the target and angular position of the target relative to the known axis;utilizing the set of visually perceptible images and the corresponding ISAR images to paint the corresponding ISAR images one or more three-dimensional representations of the target so as to produce one or more rendered composite image of the target;continuing to produce the one or more composite images until ISAR images from a fall circle of ISAR positions at three or more elevation angles are represented in the one or more composite images of the target;ascertaining correspondence between chosen target details and bright zones in the one or more composite images caused by ISAR image input.
