FIELD: radio engineering.
SUBSTANCE: method to generate a command for protection of an object against a target approaching it consists in determination of a ratio of time interval between starts of generation of differential frequency signals N 2Vofo/C on two radiolocating stations combined with an object to a time interval between starts of generation of differential frequency signals (N+4)2Vofo/C on both radiolocating signals, where N - a number higher than 1, fo - an average frequency of an emitted continuous signal with frequency modulation according to a single-sided saw-tooth linearly rising law; C, Do, Vo, Fm, dfm, - available light speed and distance, speed, frequency of modulation and deviation of frequency selected on the basis of the condition Do/Vo=fo/Fm dfm. At the same time the command for protection is generated, when the specified ratio is below the previously established number. The device for generation of a command for protection of an object against a target approaching it comprises two radiolocating stations combined with an object for detection of a moment of command issue for start of a protective ammunition, a phase detector actuating on the front with storage of a sign, a shift register, four AND elements, an OR element, a pulse generator, four counters, a divider, a delay element and a digital comparator.
EFFECT: invention provides for the possibility to expand functional capabilities of devices for generation of a command for protection of an object from a target approaching it.
