| Abstract: | The Quick -Iook algorithm is a fast-imaging processing algorithm dealing with the reduced -resolution ASR data processing .In applications where imaging processing speed is more important than resolution requirement,this algorithm can Iead to a very small-scale processing system which has very highprocessing speed .This paper discusses the Quick -Iook algorithm principl,and studies sereral key questions inthis algorithm,including the processing method to reduce the FM bandwidth,correction of the errors caused in the filtering processing,and movement compensation. Satisfactory solution to these questions are thecentral theoritical part of SAR Quick-Iook algorithm. |
