FIELD: radio engineering, communication.SUBSTANCE: determining the missing of a secure facility by a missile is carried out by measuring Doppler frequency of the missile first when the missile is located in its far detection zone and when the missile is located in its near detection zone, and comparing values of Doppler frequency measured in the far detection zone with the current values of Doppler frequency measured in the near detection zone and if the compared Doppler frequency values are identical, the missile is considered to be precisely approaching the facility, and if the Doppler frequency values measured in the near detection zone are lower than that measured in the far detection zone, the missile will miss the facility. The apparatus for determining the missing of a secure facility by a missile has a radar set for measuring Doppler frequency, a memory unit and a comparator circuit. Outputs of the radar set are connected to first inputs of the comparator circuit directly, and to the second inputs through the memory unit, and the write input of the memory unit is connected to the last output of the radar set - the output of its circuit for determining the end of measuring Doppler frequency in the far detection zone of the missile.EFFECT: reduced weight and size and cost properties of apparatus for determining the missing of secure facilities by missiles.2 cl |
