  • Method of strip-map synthetic aperture radar auto-focus processing
    Patent number: 8102299
    Abstract: A strip-map Synthetic Aperture Radar (SAR) auto-focus image generation process is provided. Batches of raw radar return data are processed in order to form batch images which each have a valid region between invalid regions. The process determines an estimate of the first derivative of a phase error at an end of the valid region, determines a time-shift corresponding to that estimate and uses that information in determining a starting point for the next batch of raw radar return data.
    Type: Grant
    Filed: October 26, 2009
    Date of Patent: January 24, 2012
    Assignee: Thales Holdings UK PLC
    Inventors: Stuart Young, Malcom Stevens
