| Abstract: | This paper firstly makes mathematical study on the relation between Doppler parameter and the SAR working configuration.Based on the above analysis,this paper provides a new Doppler parameter estimating algorithm of SAR by Radon transform,which can get accurate Doppler center and Doppler rate and avoid the problem of Doppler blur.As a result,it is a feasible Doppler parameter estimating algorithm of SAR,of which the validity is also proved by the simulation of computer at last. |
