GUIDED PROJECTILE GUIDANCE SYSTEM AND PULSE SHAPER Russian patent published in 2002 - IPC

FIELD: armament, in particular, artillery guided projectiles with a laser homing head. SUBSTANCE: the guided projectile guidance system has a control actuator, inertial gyro and a homing head including the functional gates, an OR gate inclusive, with the respective couplings; "Lock-on" input which is connected to the first input of the first AND gate and via an inverter - to the first input of the second AND gate, whose second inputs are connected respectively to the second and third outputs of the inertial gyro. The output of the first AND gate is connected to the "Compensation" input of the homing head and the third input of the first OR gate, whose second input is connected to the first output of the inertial gyro, and its output - to the input of the first power amplifier, the output of the second AND gate is connected to the second input of the second OR gate. The output of the second OR gate is connected to the input of the second power amplifier, the outputs of the first, second, third and fourth control windings of the control surface, whose second inputs are connected to the fourth input of the inertial gyro and the power source of the on-board equipment. Introduced are the third AND gate and a pulse shaper, whose first, second, third and fourth inputs are connected respectively to the "- Y", "+Y", "+Z" and "-Z" outputs of the homing head, the fifth input is connected to the output of the third AND gate, its first and second outputs are connected to the first inputs of the first and second OR gates respectively, and its third and fourth outputs are connected respectively to the inputs of the third and fourth power amplifiers, the first input of the third AND gate is connected to the output of the OR gate of the coming head, and its second input - to the "Lock- on" output of the homing head. The pulse shaper has an input bus, the first AND gate, whose first input is connected to the input bus, the second AND gate, clock pulse generator, the first pulse counter, synchronization bus and an output bus. Introduced are the second pulse counter, permanent storage and AND gates, whose total number corresponds to the quantity of the shaped output signals. The synchronization bus is connected to the input for resetting the first pulse counter, and to the count input of the second pulse counter, whose information outputs are connected to the first group of addresses of the permanent storage, whose second group of addresses is connected to the information outputs of the first pulse counter, whose count input is connected to the output of the clock pulse generator. The second output of the permanent storage is connected to the enabling input of the second pulse counter, and the first output - to the second inputs of all AND gates, whose first inputs are connected to the input bus, and the outputs are connected to the output bus. EFFECT: enhanced accuracy of guidance. 2 cl, 4 dwg
