FIELD: radar systems. SUBSTANCE: radar signal angular selector for main and lateral equisignal zones of bearing characteristic has monopulse direction finder and first module forming unit and first solving unit (P1) with are connected in series; they are connected to direction finder output for bearing error signal. To enhance noise immunity due to reduction of non-selectable portion of lateral equisignal zones, quadruple output of monopulse direction finder is connected to threshold input of second solving unit (P2) through second module forming unit and scaling amplifier connected in series; solving units P1 and P2 are combined directly by their signal inputs and their outputs are connected to direction indication signal output through inverse and direct inputs of AND gate. EFFECT: enhanced noise immunity. |
