Abstract
A method for processing synthetic aperture radar (SAR) data. The method includes the step of receiving SAR data that has been collected to provide a representation of a target scene, and dividing the data into a plurality of sub-blocks each having a plurality of pixels, each of the plurality of pixels having a coordinate and an amplitude. A transformation performed on each of the sub-blocks includes the steps of: (i) computing a mean coordinate; (ii) subtracting the mean coordinate from the pixel's actual coordinate to arrive at a modified coordinate; (iii) multiplying the modified coordinate by the amplitude to arrive at an amplitude-modified coordinate; (iv) creating a covariance matrix using the amplitude-modified coordinates; (v) performing a singular value decomposition on the covariance matrix to arrive at a vector; and (vi) associating an angle with the calculated vector.
