The method for creation of algorithms a range-doppler radar signal filtration is offered on the base of affine group representations and allowing to synthesize «plane» (two-dimensional) filters, invariant to an inner pattern and parameters of a probing signal. It allows to measure range and the Doppler speed unambiguously, and also to eliminate the phenomenon of «migration» of the purpose on range at the big times the coherent accumulation. Complexity of received algorithms depending on band-width of a signal, time of the coherent accumulation, values of ranges uncertainties on range and the Doppler frequency is estimated.
