Abstract
A new phase preserving SAR processor that solves the range dependent range cell migration problem is presented and verified theoretically in this paper. The operations involved are only Fourier transforms and multiplications. No interpolation is used, and the processor achieves O(M*log2(M)*N*log2(N)) floating point operations where M and N are arbitrary numbers of data samples in azimuth and range. The SAR processor works for squint mode as well as broadside SAR operation.
