System and method for multiple spotlight synthetic radar imaging using random beam steering |
| 摘要 |
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. |

1. A method for generating an image, wherein the image is a spotlight synthetic aperture radar (SAR) image, comprising the steps of:
directing 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 wherein the beam is steered so that the pulses are transmitted to the areas randomly and uniformly in a spatial dimension; 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. |
