FIELD: data processing. SUBSTANCE: device has reflected pulses modelling unit, time discriminator, formed by two AND gates, which have outputs connected to inputs of differential detector, inertial unit, time delay unit, range gate pulse former, three-input operational amplifier, two pulse formers, two channels for forming slope of discrimination characteristic of radio range finder. Any channel has AND gate, flip-flop, controlled inertial unit and controlled gain amplifier, connected in series. Slope of discrimination characteristic is changed at changed opening of the characteristic. EFFECT: widened functional capabilities. 4 dwg
