Method and system of launching a projectile for destroying a target

Abstract

In a system and method for launching a projectile a transmitter transmits a signal toward a projectile, a receiver receives a backscattered signal from the projectile and performs a frequency down-conversion, a signal processor detects the projectile and estimates a range, an angular position and range-rate of the projectile, a data processor estimating a flying trajectory, calculates a flying time of the projectile, and transfers a delay value to a data link device which transmits the delay value to the projectile, with the transmitting antenna transmitting a signal to the projectile to explode it at the predefined altitude near a target, and all components are located in the vicinity of the launching device.
