The authors consider in gauss approximation the optimum and quasi-optimum algorithms of processing frequency-modulated signals with unknown law of modulation. In secretive radiolocation systems the transition from adaptive optimum algorithm to quasi-optimum algorithm is based on the narrowing of the band of the a priori signal parameter uncertainty. Equations modeling nonlinear filtering unit with a system of phase lock with variable gain coefficients in circuits of back-coupling are presented. Structure of a receiving device of hidden radiolocation realizing algorithm of shared detection and filtering in the article are considered.
