CA 2245270

A method and system for detecting moving objects using azimuth streaks in synthetic aperture radar (SAR) image data are disclosed. The method and system of the present invention are directed to processing amplitude data relating to a SAR image, the first amplitude data having at least first and second indications corresponding to at least a first object moving at a substantially constant linear velocity and clutter, respectively, to separate or filter at least the first indication from the second indication, reducing/altering a spatial frequency power of the clutter corresponding to the second indication relative to a first azimuth streak power of a first azimuth streak corresponding to the first indication, and thresholding a first amplitude of the first azimuth streak to detect the first azimuth streak.
