With the development of synthetic aperture radar(SAR) technique,the requirements to the imaging precision and processing speed of SAR system is more and more hard.The operational amout of SAR imaging processing is huge.It is an usual parallel processing method to partition the SAR data,in which the large grained partition has favorable expansibility because the processing among each data block can be independent.This paper analyzes the change of operational amout of imaging processing for each data block after adopting large grained partition,and through comparison, we find that can remarkably reduce the operational amount of single data block imaging processing and the total operational amount if partition well,which will be very useful for engineering practice.
