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.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to launching of projectiles for destroying targets at a distance from a launching apparatus. More particularly it relates to methods and systems for launching from launching apparatuses of projectiles which are provided with detonators exploding in the vicinity of targets.[0002]Conventional detonators explode in response to a strike against an object. In these cases, a part of energy of explosion propagates in a direction of movement of a projectile, for example into a ground or a wall and is actually lost without inflicting destructive actions around a point of the strike. This result is satisfactory when it is necessary to destroy an object and to make a hole in it. However, when the objective is to physically destroy an enemy, it is desirable to cover a maximum area without losing a striking force. For this purpose it is necessary to trigger detonation at a certain height, which leads to a much higher hitting result.[...

AI Technical Summary

Benefits of technology

The present invention provides a method and system for launching a projectile for destroying a target. The method involves estimating the trajectory of the projectile after its launch, determining the desired time of detonation at a desired height, and transmitting the information to the projectile for detonation. The entire process is carried out in the vicinity of the launching apparatus, making it difficult for electronic detection and interception by adversaries. The system includes a launching apparatus, means for estimating the trajectory of the projectile, a transmitter, a receiver, and a signal processor for detecting and estimating the presence, range, angular position, and range-rate of the projectile, and a data processor for calculating the flying time and transferring a delay value to the projectile. The system can send a signal to the projectile to explode at a specific point near a target. The technical effects of the invention are improved accuracy, efficiency, and safety in launching projectiles for destruction purposes.

Problems solved by technology

For this purpose it is necessary to trigger detonation at a certain height, which leads to a much higher hitting result.

The disadvantage of a mechanical detonator is that its time of detonation is set up before shooting under presumption that its whole flight will take place along a preliminarily calculated trajectory.

Further non-mechanical detonators operate with electronic measurement of a height of flight and explode when the projectile reaches a desired height during its descending flight.

However, detonators with radio sensors can be disabled with radio interference during approach of a point of detonation.
