Abstract: The paper investigated the possibilities of newly formed dual system SARH (Semi-active radar homing) missiles SA-6 mid-range category, on standard manoeuvrable targets.The system was set up as a dual-cooperative guidance of the first launched (guided-slave) missile from second launched missile (leading-master), with a time delay of 3s. Angle position of target is measuring  using two existing RHH, which together with additional illuminators on missiles, represent two active seekers, with a period of mutual scanning and with changing the roles-status of 1s. Also, missiles synchronously communicate between each other through free caudal antenna, when it is situation based on the smaller current error, determines the status of a missile. Proces of coupled guidance is modeled with specially designed program in MATLAB with appropriate adjustment AD, AL and effective radius of action Warhead. Missiles are guiding in calculated point of overtaking with clasical method PN with changing the angle of launch SPLV, by changing the distance, altitude and speed targets and and other given parameters of flight. Simulations were examined specific conditions and regimes of shooting with one or two missiles, the correlation results and made conclusions of the most efficient mode and optimal performances of dual system homing missiles AAD.
