ABSTRACT:
This system includes, in a projectile P bearing explosive warheads 2, 4, with their firing device 3, 5, impact detectors 1, an inertial unit 6 and a computer 7. The computer 7 determines, on the basis of the signals from the detectors 1, the instant of impact To and the angle of incidence I of the projectile on the target and, on the basis of the signals from the inertial unit 6, the speed V of the projectile at the instant of impact. Using the data V, I and the data on the type of target C, the computer 7 determines, in real time, the optimum delay with respect to the instant To for the firing of each warhead, and applies this delay to the firing command.
