Abstract
The invention is concerned with the techniques of firing simulation. Its main subject is a method of and device for firing training, in which optical simulation of firing as a function of at least the firer's aim and of reference data comprising at least a reference line of sight and a target distance, is characterized by the fact that account is taken in the simulation of prerecorded terrain data defining at least three ground planes perpendicular to the line of sight, vertical plane containing the said three ground planes being located around the target, in front of the target, and behind the target, with respect to the firer.
Claims15
A method of gunnery training including the simulation of the firing of a projectile from a gun up to and including the point of impact of the fired projectile which comprises optically representing the trajectory of said projectile as a function of the aiming of the gun and of reference data which includes a reference line of sight from the gun to the target and the distance to the target from the gun;
- determining the point of impact of said projectile as defined by its simulated intersection with simulated terrain data which defines at least three ground planes perpendicular to the vertical plane containing the line of sight, said ground planes located respectively around the target, in front of the target, and behind the target, with respect to said gun;
- and providing an optical indication of said point of impact, with said optical indication being shown either as a visible or hidden impact depending on the position of the point of impact on the ground planes with respect to the target outline.
A method of gunnery training including the simulation of the firing of a projectile from a gun up to and including the point of impact of the fired projectile which comprises optically representing the trajectory of said projectile as a function of the aiming of the gun and of reference data which includes a reference line of sight from the gun to the target and the distance from the gun to the target;
- said reference date including simulated terrain data which defines at least one ground plane which is distinct from the plane perpendicular to the vertical plane containing the line of sight, which ground plane is also distinct from the plane perpendicular to the line of sight at said target distance;
- determining said simulated projectile trajectory up to said point of impact from said reference data and from the aim of said gun upon the firing of said simulated projectile;
- and providing an optical indication of said point of impact, with said optical indication being shown either as a visible or hidden impact depending on the position of the point of impact on the ground plane with respect to the target outline.
In a gunnery training system capable of providing training by simulated firing of a projectile onto an actual target and landscape which includes optical means for signting the target and surrounding terrain and for producing a luminous spot indicative of the simulated flight of said projectile, which spot is superimposed by said optical means on said surrounding terrain, computer means for producing electrical signals for controlling the position and intensity of said luminous spot according to prerecorded data, control means for feeding ballistic data to said computer means, the method of providing an optical indication of the actual point of impact of said simulated projectile on said target or on said surrounding terrain, which comprises the steps of providing simulated terrain data into said computer means which defines at least three ground planes perpendicular to the vertical plane containing the line of sight to said target, said three ground planes located respectively around the target, in front of the target, and behind the target;
- and providing a visual indication in said optical means from said computer means as to the precise point at which the trajectory of said simulated projectile intersects one of said three ground planes whereby corrective measures may be taken by the gunner in accordance with said visual indication, said visual indication being shown either as a visible or hidden indication depending on the position of the point of impact on the ground planes with respect to the target outline.
