| 英文摘要 | For large-scale synthetic aperture radar (sar) data, it is difficult to achieve sar imagery in a timely manner using traditional imaging algorithms. subaperture architecture is introduced to a chirp-scaling algorithm to process large-scale sar data. by means of the subaperture partition, the real data can be processed in parallel based on heterogeneous graphics processing unit-central processing unit architecture. the principle of subaperture partition is not only discussed, but also the closed form of the overlap rate for a subaperture combination under the mode is first theoretically presented, which provides a foundation for airborne real-time data processing. finally, simulation and real data experiments validate the proposed approach.
