Abstract
A spotlight synthetic aperture radar (SAR) image is generated by directing randomly a beam of transmitted pulses at a set of two or more areas using a steerable array of antennas. Each area is illuminated by an approximately equal number of the transmitted pulses. Then, a reconstruction procedure is applied independently to received signals from each area due to reflecting the transmitted pulses to generate the image corresponding to the set of areas.
Claims5
A method fir generating an image, wherein the image is a spotlight synthetic aperture radar (SAR) image, comprising the steps of:
- directing randomly a beam of transmitted pulses at a set of two or more areas using a steerable array of antennas, wherein each area is illuminated by an approximately equal number of the transmitted pulses;
- and
- applying independently a reconstruction procedure to received signals from each area due to reflecting the transmitted pulses to generate the image corresponding to the set of areas.
