Mono and bi-static SAR Image Synthesis Algorithm Improvement on Multi-processor/Multi-core Computers.

摘要

SAR image synthesis with wider bandwith (hence range resolution) require sharing the computation in sub-bands becausernantenna pattern varies within the bandwidth. Furthermore the wide integration in azimuth requires wide antenna patternrnhence interactions with the carrier aircraft body. We present here the computation in sub-bandwidth by concurrent processesrnand sharing of the mocomp time-variation by concurrent threads within each process. This organising is adaptedrnto the present tendency to increase the number of cores without significant increase in each core velocity.
