摘要：
An efficient tomographic algorithm is studied according to the high resolution imaging capability on small target terrain during the spotlight mode SAR procedure in this paper. By simplifying the procedure of Fourier reconstruction, reducing the A/D rate and PRF, implementing initial phase compensation facilitating the hardware materialization, this tomographic algorithm for spotlight mode SAR greatly benefits the imaging processing efficiency. Necessary explanations, deductions. figures, tables and simulation results are given out.
