Atomic functions in the two-stage digital signal processing scheme of SAR

Two-stage signal processing method in SAR is used for frequency matching at the input and the output of digital system. In that case, digital synthesizing process pass with low sampling frequency, that reduce requirement for digital processing system. In the process of forming radar image for decreasing the sidelobe level weighting functions are used. In the report, a new class of weighting windows, based on the theory of atomic functions, offered for use. Numerical experiment results are presented. Efficiency of the new method is shown.
