The substantiation of use of complex signals in a radar-location is resulted. The basic problems are designated at use of complex phase-shift keyed signals: increase of side lobe at an optimum filtration and power losses at sub-optimal filtrations. Synthesis the sub-optimal filter of compression in which basis use of a method of return pulsations. The basic purpose of application of such filter is the sanction of the compromise between problems designated above. The filter offered can be used in the equipment of primal processing the information of survey and landing radar stations for allocation of a useful signal on a background of own noise of the reception path, reflections and interference from other means of a radio-electronic complex. Theoretical substantiation of a MRP is submitted, processes of formation complex phase-shift keyed signal are considered, and also the mathematical model of this signal is synthesized. Mathematical adjustments for pulse and transfer characteristics sub-optimal filter of compression are received, and also oscillograms of a target signal of this filter are submitted.
