Abstract

Method and firing simulator for practicing aiming with the use of a laser firing simulator and of a retroreflector on the target side, as well as a simulator for carrying out this method. On triggering of the simulated firing, the target distance, the velocity of the target relative to the line of sight and the aiming-off allowance are measured, and the position of the hit is computed therefrom after the elapse of the projectile flight time.

Claims

1. A method for practising aiming with a firearm, using a laser firing simulator and a retroreflector on the target side, comprising the steps of determining the hit position achieved after the elapse of the projectile flight time by measuring the target in relation to a reference line extending from said simulator on the basis of a target distance measurement undertaken on simulated discharge of the projectile, wherein the relative angular velocity of the target to the reference line and the aimingoff allowance of the firearm are measured before the elapse of the projectile flight time and the hit position is determined therefrom after the elapse of the projectile flight time.

2. A method as in claim 1, wherein the line of sight is employed as reference line.

3. A method as in claim 1, wherein the angular velocity of the line of sight is determined and is taken into account in the determination of the hit position.

4. A method as in claim 3, wherein measurement of angular velocity of the target, measurement of the aiming-off allowance and measurement of angular velocity of the line of sight takes place at the time of the discharge of the projectile.

5. A firing simulator for practising aiming with the use of a taget equipped with a retroreflector which simulator comprises a laser beam emitter for emitting light in the direction of said target, a receiver for the laser light reflected by the target, a laser range finder responsive to said reflected light, means for detecting the position of light reflected by the target relative to a reference line, a trigger for triggering a simulated discharge of a projectile, an evaluating arrangement for the determination of the hit position after the elapse of projectile flight time, measurement means for measurement of the angular velocity of the target in relation to the reference line and of aiming-off allowance, said measurement means being connected with the evaluating arrangement in such a manner that their measurement results related to the time of discharge of the projectile can be coupled to the evaluating arrangement.

6. A firing simulator according to claim 5, wherein a receiver resolving the direction of reception establishes the velocity of the target relative to the line of sight.

7. A firing simulator according to claim 6 wherein the receiver comprises a video camera.

8. A firing simulator according to claim 5, wherein said means for detecting the position of the light reflected by the target includes means for measuring the distance of the target.

9. A firing simulator according to claim 8 wherein said simulator is connected with a weapon component participating in the setting of the aiming-off allowance of the weapon, and includes arrangements for the resetting of the laser beam emitter by the aiming-off allowance.

10. A firing simulator according to claim 8 wherein the laser beam emitter is designed for large-area target field illumination.

11. A firing simulator according to claim 10, wherein the laser beam emitter is designed for target field illumination of approximately constant width independent of distance.

12. A firing simulator according to claim 10, wherein the width of the beam cross-section in the target region is smaller than the width of the maximum target field to be illuminated, and wherein the laser beam emitter is designed for lateral beam deflection.

13. A firing simulator according to claim 12, wherein the laser beam emitter includes a beam splitter, and wherein a partial beam passes through an arrangement for lateral beam deflection, while the other beam remains in a state of rest.

14. A firing simulator according to claim 12, wherein the lateral beam deflection can be triggered by the absence of a reflection signal.

15. A firing simulator according to one of claim 8, further comprises a monitor which images the target field and a hit mark.
