Abstract. Results of processing of signals of quasicontinuous radiation and with linear frequency modulation by the radar station accompanying group air object are presented. Possibility of superresolution of group objects on range and speed in pulse volume is experimentally confirmed with classical and coherent methods of the autoregression digital spectral analysis, and also the methods based on the theory of statistical decisions. Features of superresolution of signals after preliminary digital processing of signals in the conditions of their distortions are given in a send-receive path of RLS, weighing of a bending-around pack of impulses in time, reflections from a spreading surface, local subjects and screw components.
Keywords: superresolution, group air object, linear prediction, theory of statistical decisions, linear frequency modulation, vector of weight factors, time function, spectral function, range strobe, frequency filter.
