Abstract

------25/10/2023------(OCR) According to one embodiment, the image processing of an inverse synthetic receiver (ISAR) radar system includes receiving an ISAR image from the inverse synthetic receiver system radar system, wherein a standard deviation contour is generated from the ISAR image, wherein the standard deviation contour represents the standard deviation of the ISAR image. The standard deviation contour is normalized to form a normalized standard deviation contour pattern. A mean contour is generated from the ISAR image, wherein the mean contour represents the deviation of the mean of the ISAR image. The mean contour is normalized to form a normalized mean contour pattern. The standard deviation contours and the normalized mean contours are then combined to form a normalized range contour pattern. The normalized range contour pattern may then be processed to classify targets in the ISAR image. ------------ DC60 (04/09/52) According to an embodiment of the invention, the image processing of an inverse synthetic receiver (ISAR) radar system comprises receiving an ISAR image from an inverse synthetic receiver system radar system, wherein the standard deviation contour represents the standard deviation of the ISAR image. The standard deviation contour is normalized to form a normalized range contour pattern. A mean contour is then generated from the ISAR image, wherein the mean contour represents the deviation of the mean of the ISAR image. The mean contour is normalized to form a normalized mean contour pattern. The standard deviation contours and the normalized mean contour patterns are then combined to form a normalized range contour pattern. The normalized range contour pattern may then be processed to classify targets in the ISAR image. A standard deviation plot is generated from the ISAR image, where the standard deviation plot represents the standard deviation of the ISAR image, and the standard deviation plot is normalized to generate a standard deviation plot pattern. A mean plot is generated from the ISAR image, where the mean plot represents the deviation of the mean of the ISAR image, and the mean plot is normalized to generate a normalized mean plot pattern. The standard deviation plot and the baseline mean plot are then combined to generate a normalized range sum plot pattern. The baseline range sum plot is then processed to classify targets in the ISAR image according to the pattern representation of artifact. In terms of image processing, an inverse synthetic receiver (ISAR) radar system consists of receiving an ISAR image from an inverse synthetic receiver radar system. A standard deviation plot is generated from the ISAR image, where the standard deviation plot represents the standard deviation of the ISAR image, and the standard deviation plot is normalized to generate a standard deviation plot pattern. A mean plot is generated from the ISAR image, where the mean plot represents the deviation of the mean of the ISAR image, and the mean plot is normalized to generate a pattern. The baseline mean plot is then combined with the baseline mean plot to form a sum of baseline range plots. The sum of baseline range plots is then processed to classify the targets in the ISAR image.
