Research on Azimuth Optimization Algorithm for FMCW SAR
Frequency modulated continuous wave synthetiC aperture radar (FMCW SAR) has the advantages such as small cubage,light weight,cost-effective,highresolution,etc.So there is a growing interest in the frequency modulated FMCW SAR.Firstly,aiming at the characteristics of FMCW SAR,the signal model was analyzed in detail. Then the azimuth matching filtering function is discussed.In order to form the accurate image as well as avoid the large calculation amount,the azimuth optimization algorithm which divides the scene into segments and uses the dynamic state azimuth matching filtering function is presented,and the criterion which is used to divide the scene into segments is given. At last,the simulation proves the algorithm is feasible.
