  • Inverse synthetic aperture radar image processing
    Patent number: 8232908
    Abstract: According to one embodiment, inverse synthetic aperture radar (ISAR) image processing includes receiving an ISAR image from an inverse synthetic aperture radar. A standard deviation profile is generated from the ISAR image, where the standard deviation profile represents a standard deviation of the ISAR image. The standard deviation profile is normalized to form a normalized standard deviation profile. A mean value profile is generated from the ISAR image, where the mean value profile represents a mean value deviation of the ISAR image. The mean value profile is normalized to form a normalized mean value profile. The normalized standard deviation profile and the normalized mean value profile are combined to form a sum normalized range profile. The sum normalized range profile may be processed to classify a target in the ISAR image.
