  • Synthetic aperture radar (SAR) imaging system
    Patent number: 8344934
    Abstract: One embodiment of the invention includes a synthetic aperture radar (SAR) system including a receiver configured to receive a plurality of reflected radar pulses corresponding to a plurality of radar transmission pulses having been reflected from a target region. A processing controller divides the target region into a plurality of tiles at a highest data layer and each of the plurality of tiles into a plurality of sub-tiles corresponding to one of a plurality of data layers and iteratively processes a portion of pulse data corresponding to a given tile associated with a higher data layer to generate pulse data corresponding to a given sub-tile in a lower data layer. An image processor is configured to generate a radar image of the target region based on the pulse data corresponding to each of the plurality of sub-tiles associated with a lowest data layer of the plurality of data layers.
