Abstract

A method is provided for calculating the bursting point of at least one projectile fired at a target object, involving measuring the position of the projectile, estimating the position of the projectile, estimating the speed of the projectile, measuring the position of the target object, estimating the position of the target object, estimating the speed of the target object, calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object, and communicating the bursting points for the projectile to the projectile. A computer program, a computer system, and a weapons system are also provided.

First claim

The invention claimed is:

1. A method for calculating a bursting point of at least one projectile fired from an air defense gun barrel at a target object, comprising:
measuring a position of the projectile,
estimating a position of the projectile,
estimating a speed of the projectile,
measuring a position of the target object,
estimating a position of the target object,
estimating a speed of the target object,
estimating a trajectory of the target object,
calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object,
communicating the bursting points for the projectile to the projectile.

2. The method for calculating the bursting point of at least one projectile fired at a target object according to claim 1 , wherein the target object is an aerial target object.

3. The method for calculating the bursting point of at least one projectile fired at a target object according to claim 2 , wherein the trajectory of the projectile is estimated for calculating the estimated position of the projectile and the estimated speed of the projectile.

4. The method for calculating the bursting point of at least one projectile fired at a target object according to claim 1 , wherein the projectile is controllable.

5. The method for calculating the bursting point of at least one projectile fired at a target object according to claim 4 , wherein control information for the projectile is communicated to the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object, where the control information comprises control commands for guiding the projectile towards the target object.

6. A non-transitory computer storage medium comprising program code wherein, when the program code is executed on a computer, the computer executes a method for calculating a bursting point of at least one projectile fired from an air defense gun barrel at a target object, the method comprising:
measuring a position of the projectile,
estimating a position of the projectile,
estimating a speed of the projectile,
measuring a position of the target object,
estimating a position of the target object,
estimating a speed of the target object,
estimating a trajectory of the target object,
calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object,
communicating the bursting points for the projectile to the projectile.

7. A computer system comprising a computer, wherein the computer is configured to execute a computer program so that the computer a method for calculating a bursting point of at least one projectile fired from an air defense gun barrel at a target object, the method comprising:
measuring a position of the projectile,
estimating a position of the projectile,
estimating a speed of the projectile,
measuring a position of the target object,
estimating a position of the target object,
estimating a speed of the target object,
estimating a trajectory of the target object,
calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object,
communicating the bursting points for the projectile to the projectile.

8. A weapons system comprising gun barrel weapons, a fire control, and sensor systems for measuring a target object and projectiles, the fire control comprises a computer system comprising a computer, wherein the computer is configured to execute a computer program so that the computer executes a method for calculating a bursting point of at least one projectile fired from an air defense gun barrel at a target object, the method comprising:
measuring a position of the projectile,
estimating a position of the projectile,
estimating a speed of the projectile,
measuring a position of the target object,
estimating a position of the target object,
estimating a speed of the target object,
estimating a trajectory of the target object,
calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object,
communicating the bursting points for the projectile to the projectile.

9. The weapons system according to claim 8 , wherein the sensor system comprises at least one radar.
