Abstract
Abstract The simulation device provides training in the firing of rockets or guided missiles by means of a shoulder weapon. As soon as a shot is fired, the firer's field of view is occulted by a shutter. The aim at the instant of firing and the point of impact with respect to the target are displayed on an instructor's video screen. The target can be of a fictitious type generated by a computer and produced within the field of view of both the instructor and the firer at the same time. In the case of a real target, an index can be controlled by the instructor in order to locate the target and follow its progress up to the instant of firing. The result of the firing operation is judged according to the position of the point of impact with respect to the fictitious target or with respect to the index. The choice of the mode of operation is made on a control desk.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
216 words
A simulation device for training in the operation of shoulder weapons or the like, comprising a weapon having a sighting line which can be oriented by the firer and is fitted with an optical unit for providing the firer with a field of view comprising a firing ground and a target, and means for initiating fictitious firing of a projectile by the firer, means for transmitting an image of said field of view picked up through the optical unit to an instructor station and for projecting said field of view on to a display screen, and a computer functionally connected to the optical unit for determining the position of impact of the projectile in the plane of the target, wherein said simulation device comprises means for displaying either a target locating contour in superimposition on an image of the target displayed on the instructor screen or a fictitious target on the instructor screen, occulting means for concealing the field of view from the firer at the instant of firing a shot while allowing the display target to remain on the screen of the instructor station at the time of occultation of the firer's field of view, and means for displaying the impact position with respect to the target on the display screen of the instructor station.
Claim 2
Dependent Claim

A simulation device for training in the operation of shoulder weapons or the like, comprising a weapon having a sighting line which can be oriented by the firer and is fitted with an optical unit for providing the firer with a field of view comprising a firing ground and a target, and means for initiating fictitious firing of a projectile by the firer, means for transmitting an image of said field of view picked up through the optical unit to an instructor station and for projecting said field of view on to a display screen, and a computer functionally connected to the optical unit for determining the position of impact of the projectile in the plane of the target, wherein said simulation device comprises means for displaying either a target locating contour in superimposition on an image of the target displayed on the instructor screen or a fictitious target on the instructor screen, occulting means for concealing the field of view from the firer at the instant of firing a shot while allowing the display target to remain on the screen of the instructor station at the time of occultation of the firer's field of view, and means for displaying the impact position with respect to the target on the display screen of the instructor station.
Claim 3
Dependent Claim
47 words
A device in accordance with claim 1, wherein the means for displaying on said screen a target locating contour can be controlled from the instructor station to follow the movements of the target and indicate the location of the target at the instant of firing a shot.
Claim 4
Dependent Claim
64 words
A device according to claim 2, wherein the target locating contour has a size in relationship with the target dimensions and wherein said contour can be controlled in positions and in dimensions from the instructor station, to follow the modifications of the dimensions of the image of the target displayed on the instructor screen due to the movement of the target in the landscape.
Claim 5
Dependent Claim
44 words
A device according to claim 1 or claim 2, wherein said device comprises means for forming a fictitious target which appears in the firer's field of view and is superimposed on the firing ground, to constitute on the instructor screen the fictitious displayed target.
Claim 6
Dependent Claim
30 words
A device according to claim 1, wherein the instructor station is provided with means for controlling the fictitious target at least in position, orientation and dimensions on the display screen.
Claim 7
Dependent Claim
59 words
A device in accordance with claim 5 wherein the instructor station is provided with a control desk comprising means enabling the instructor to choose between at least two operating modes, in one case with a real target forming part of a landscape observed by the firer and in the other case with a fictitious target superimposed on said landscape.
Claim 8
Dependent Claim
33 words
A device in accordance with claim 6, wherein the control desk is provided with means for recording in the computer memory the characteristics of a plurality of fictitious targets and their respective displacements.
Claim 9
Dependent Claim
52 words
A device in accordance with claim 6, characterized in that the instructor station comprises control means for aligning a cross produced by image-generating means on the reticle of the firer's field of view and the reticle inserted on the screen of the instructor station with the alignment cross reproduced on said screen.
