| Abstract: | High resolution is one of the important developing directions of Synthetic Aperture Radar (SAR). A study of the Chirp Scaling Algorithm(CSA) for the spotlight SAR image formation is made in this paper. The CSA's fundamentals and realization course are discussed in detail,and the mathematic functions of all signal domains in the calculation process are offered. CSA's characters and applications are introduced briefly. At last,the point targets are simulated,and the parameters of the simulation system and the simulation result are presented. |
