Abstract

A method is provided to improve the impact point for at least one subsequent projectile fired towards a target, launched after an initial projectile, where the subsequent projectiles can alter their course, based on information on the previous projectiles' time of automatic detonation, to improve the ability to detect a target. A projectile and a fuse are also provided.

First claim

The invention claimed is:

1. A method to alter an impact point of a projectile launched at a target, comprising
launching a first projectile at a target,
launching a second projectile at the target, the second projectile having knowledge of a time when the first projectile will automatically detonate,
detecting the target with the first projectile and transmitting target position information to the second projectile with the first projectile,
automatically detonating the first projectile at an end of a programmed time period, and
altering a course of the second projectile based on information regarding the time of automatic detonation of the first projectile.

2. The method to alter the impact point of the projectile according to claim 1 , comprising setting a course of the second projectile based on received target position information, and detonating the second projectile on an external command or at an estimated impact point based on an estimated trajectory of the target.

3. The method to alter the impact point of the projectile according to claim 2 , comprising estimating the target's trajectory using the target's position information.

4. The method to alter the impact point of the projectile according to claim 3 , comprising using the estimated target trajectory to calculate an optimal impact point for detonation.

5. The method to alter the impact point of the projectile according to claim 2 , comprising using a signal transmitted from a fire control system as an external command.

6. The method to alter the impact point of the projectile according to claim 1 , wherein the target position information comprises a direction of the target relative to the first projectile.

7. The method to alter the impact point of the projectile according to claim 1 , wherein the target position information is a specified location in a three-dimensional positioning system.

8. The method to alter the impact point of the projectile according to claim 1 , wherein the target position information is used to direct a sensitivity of a sensor inside the second projectile.

9. The method to alter the impact point of the projectile according to claim 8 , further comprising changing the sensitivity of the sensor from omnidirectional, 360 degrees, to sensitivity in a segment of less than 90 degrees.
