METHOD FOR ACQUIRING THE COORDINATES OF A TRIGGER POINT OF A PROJECTILE AND FIRE-CONTROL SYSTEM IMPLEMENTING THE METHOD

摘要

A method for acquiring the coordinates of a trigger point of a projectile above a field part on which a target is located, including: emission of at least one laser pulse having a pre-determined duration and directed towards the target; reception of the images reflected with a receiver equipped for the synchronous visualization of the laser pulses originating from a piece of observation of the field part; recovery of the coordinates of a desired trigger point when the operator has chosen a location after the piece of observation was moved. The invention also relates to a fire-control system using such a method.

1. A method for acquiring the coordinates of a trigger point of a projectile or of a burst of projectiles on a trajectory and above a field part on which a target is located, wherein the method comprises the following steps:
emitting from a laser source at least one laser pulse having a predetermined duration and directed towards the field part where the target is located, receiving the images reflected by the field part with a receiver equipped with means for the synchronous visualization of the reflection of the laser pulses under the form of a piece of observation of the field part, the width of the piece of observation being adjustable by selecting a duration for the laser emission or reception, and the distance of the piece of observation with respect to the receiver being adjustable by adjusting a delay between the emission and the reception of the laser pulse, recovering the coordinates of a trigger point when the operator has chosen a location after having moved the piece of observation with respect to the receiver and adjusted the width of the piece of observation, the trigger point being within the piece of observation.
