FIELD: radio engineering, communication.
SUBSTANCE: protective ordnance to be launched is selected based on the sign and value of mismatch between onset and detection, at spaced-apart radar stations for determining the time for issuing commands to launch the protective ordnance, of signals at frequency NFdo, where N is a number equal to or greater than 3, which depends on the range and speed of the target, and the ordnance is fired towards the target approaching the radar station when the radar station detects signals with frequency Fdo=2Vofo/C, where C is the speed of light, Vo is the radial speed of the protective ordnance, fo is the average frequency of the emitted continuous signal with frequency of modulation on a one-sided saw-tooth linearly rising law. The apparatus for determining a protective ordnance to be launched has two radar stations for determining the time for issuing commands to launch the protective ordnance, a front-triggered phase detector with sign storage, a shift register, six AND elements, an OR element, a pulse generator, a pulse counter, a delay element and three digital comparators, as well as a generator of known digital numbers for the apparatus, which is based on known radar stations for determining the time for issuing commands to launch the protective ordnance with a time interval measuring device and a code converter or a radar station for measuring the initial speed of the missile with a code converter.
EFFECT: broader functional capabilities.
