AIRCRAFT SIGHTING SYSTEM FOR CLOSE AIR COMBAT Russian patent published in 2015 - IPC F41G3/22 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to means of sighting at the planes. The invention comprises an onboard radar station, a signal processor, a display, and a communication unit with the missiles, an attack mode switch, the sensors of flight altitude and aircraft bank, the switch of displacement of field of view, a processor of sighting control, a unit of indication of target on the angular position and a unit of indication of target on the angular velocity. The unit of indication of target on the angular position of the target comprises n threshold devices, a setpoint device of signals, the OR element, the subtractor, the first and second diodes. And the first and second inputs of the unit of indication of target are respectively the first inputs of n threshold devices and the second input of the subtractor. The outputs of the first and second diodes and the subtractor are respectively the first, second and third outputs of the unit of indication of target on the angular position of the target. The unit of indication of target on the angular velocity of the target movement comprises the first NOT element, a shift register, a generator of signals, n AND elements, n second NOT elements, n counters, a subtractor, the first and second diodes. And the first, second and third inputs of the unit of indication of target on the angular velocity of the target movement is the input of the first NOT element and the first inputs of the first and second keys. The outputs of the first, second devices and subtractor are respectively the first, second and third output of the unit of indication of target.

EFFECT: reducing the time of sighting.
