ELECTRONIC UNIT OF TWO-CHANNEL SEMI-ACTIVE LASER SELF-GUIDANCE HEAD Russian patent published in 2013 - IPC F42B15/01 

FIELD: weapons and ammunition.

SUBSTANCE: electronic unit (EU) comprises four adders, four linear pickup circuits (LPC) and signal PDM circuit. Electronic unit first and second inputs are connected to first and second inputs of photo receiver. Signal PDM circuit four outputs are connected to projectile steering drive. First adder first input is connected with electronic unit first input, adder second input is connected with EU third input via signal "Compensation" of inertial gyro and adder output is connected with first input of self-guidance head gyro. Gyro correction second input is connected to EU second input. First LPC, second adder, second LPC and third adder are connected in series. Third adder output is connected to PDM circuit first input. Third LPC is connected in series with fourth adder with its output connected to PDM circuit second input. Fourth LPC input is connected to EU third input while fourth LPC ouputis connected with second adder second input. First and third LPC inputs are connected with EU first and second inputs, respectively. Third and fourth adder second inputs are connected with angular velocity transducer first and second outputs that makes EU fourth and fifth inputs, respectively.

EFFECT: higher efficiency and accuracy of fire.
