- W2004996850 abstract "The spotlight mode SAR (SPSAR) image reconstruction problem may be solved using a backprojection algorithm in the spatial domain while the radar return signals being recorded. The resulting SPSAR algorithm, studied by Desai and Jenkins, permits parallelization of the image reconstruction, and obviates a costly Fourier-domain resampling step. We show that by using a radar signal of a specially designed form with backprojection, the reconstruction becomes extremely simple, eliminating the need for Fourier processing of the return signals, by incorporating a derivative of a Hilbert transform into the emitted signal. We show some simulation results using this new method. We also briefly discuss an algorithm for reconstruction of a function residing on a hemisphere from its radar returns without geometric approximation or distortion.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
