FIELD: weapons and ammunition.
SUBSTANCE: group of inventions refers to a method and device of a command formation for launching of protective ammunition and to the application of this device as a radar station of a target speed measurement, as a radio fuse and as a time interval meter of a target passing the known distance. The method involves determination of a moment of the command generation for launching of protective ammunition specified by starting of appearance and detection of a signal of specific differential frequency by the radar station. The command for launching of protective ammunition is formed only when duration of the second time interval is equal to duration of a half of the first time interval. The device contains an antenna, the first and the second mixers, a transmitter of a continuous signal with a frequency-shift by one-sided saw-toothed liner increasing rule, a differential frequencies filter, a continuous frequency generator, a broadband filter, a limiting amplifier, a narrow-band pass filter, an amplitude detector, a comparator, a pulse former, the second generator of continuous frequency, an analogue adder, a shift register, a count pulse generator, an updown counter, a digital comparator, a biased multivibrator, three AND elements, two OR elements, a halver, a commutator, a memory unit, a decoder. The antenna input for the transmission is connected to a high-capacity output of the signal transmitter by a delay component.
EFFECT: technical result consists in an increased reliability of superspeed targets detection.
