Claim One:
1. A method for generating images comprising: receiving, via a radar, radar return signals from an area of interest at a number of radar positions; acquiring radar return data and positional data from the radar; each of the positional data forming a positional record in an array of positional records; each of the radar data comprising a first number of radar data points in the frequency domain; forming an image comprising an array of pixel values comprising: a) randomly setting a percentage of the first number of radar data points to zero; thereby selecting subsets of receive channels for removal from the complete first number of radar data points; b) transforming the first number of radar data points into time domain signature data; c) differentiating the signature data in the time domain to create a new set of signature data indicating the location of moving targets; d) forming an image by processing the signature data utilizing an imaging subsystem that combines the positional and signature data to form the moving target indication image utilizing one of a back-projection algorithm or range migration algorithm; e) saving the pixel values for each of the image pixels into a composite image; f) repeating the step of randomly setting a percentage of the radar data points to zero; g) transforming the first number of radar data points into time domain signature data; h) differentiating the signature data in the time domain to create a new set of signature data indicating the location of moving targets; i) forming a second image by processing the signature data utilizing an imaging subsystem that combines the positional and signature data to form SAR imagery utilizing one of a back-projection algorithm or range migration algorithm; j) comparing the pixel values at each of the pixel locations in the second image to the corresponding pixel values of the composite image; k) replacing the pixel values in the composite image if the pixel value is less in the second image than it is in the composite image; l) repeating steps i) through k) for a pre-determined number of iterations; whereby the composite image is outputted with reduced sidelobes and noise.
