  • Patent number: 4662845
    Abstract: A target system for laser marksmanship training devices is comprised of one or more photodetectors mounted on a target and sensitive to one or more pulses of the operating wavelength of a laser beam simulating the projectile of a weapon. An amplifier increases the power output of the photodetectors, and a frequency selective transducer is operated from the amplified output of the photodetectors. The transducer is attached and acoustically coupled to the target and produces a vibration signature simulating the vibration characteristics of a weapon-fired projectile striking the target. A microphone sensitive to the vibration signature of the transducer is acoustically coupled to the target, and a drive mechanism lowers the target out of the field of view of the weapon when the microphone receives a hit-indicating vibration signature from the transducer.

  • Patent number: 4640514
    Abstract: Designs of prior art art not usable in efficient dry-run target practice with hand firearms. The greatest drawbacks are, for instance, that it is not possible by the method to monitor the result of the dry-run training; that the method or means is not liable on ordinary guns without special measures or not at all or the method is so complicated that its implementation in practice causes that the means is too expensive to be in the personal possession and use of shooters. In order to eliminate said drawbacks, the invention is mainly characterized in that by a transmitter/receiver means attachable to conventional arms is emitted an optical beam towards a surface serving as the target which is set off from its surroundings due to its optic radiation reflecting properties relative to those of its surroundings, the hitting or missing of the beam being observed with the receiver on the basis of the return beam.

  • Patent number: 4592554
    Abstract: Equipment to simulate the firing of at least one projectile from a gun at a target such that a beam of electromagnetic radiation replaces the projectile trajectory. A hand held simulator includes a projector for generating such a beam of light, the power of which is no greater than 40 mW, in response to the operating of a trigger. If aimed correctly at the target, which is retroreflective, the beam is reflected back to the equipment and the reflected beam is received by a receiver which includes a collection of components connected in series. In view of the low power of the beam and the large distance over which the equipment is designed to operate, the components forming the receiver are designed to differentiate a fairly weak signal form the background light.

    Abstract: A firing weapon is associated with a laser radiation source mounted in proximity to the weapon and also with a detector which is sensitive to the laser radiation. The orientation of the radiation is adjusted independently of the aiming of the weapon in order to carry out continuous detection of the target as a result of detection of radiation by the detector after reflection from the target. The orientation and the time of transit of radiation between source and target are utilized in order to obtain target data relating to position in elevation and in azimuth as well as distance of the target. The data are processed in order to orient a real shot or in order to compare the data quantitatively with the position of a simulated projectile which follows a fictitious trajectory.

  • Patent number: 4315689
    Abstract: A shot simulator using laser light is disclosed for simulating guided missiles. A laser transmitter coupled to a target tracking sight emits differently coded laser signals having different angular deviations from the line of sight repeatedly during at least a substantial portion of the time of flight of the simulated missile. A receiver for laser light reflected from the target is coupled to decoding and analyzing means for calculating the momentary angular deviation of the sight from the target and evaluating these deviations over a substantial portion of said time of flight. Hit indicating means are controlled responsive to the result of said evaluation.

  • Patent number: 4290757
    Abstract: A weapons simulator for training a marksman on an anti-armor weapon. The pons simulator includes first and second broadcasting means for projecting on a reflective display screen a background scene, a visual target, and an infrared target spot in alignment with the visual target, and a two-axis laser spot positioning servo system for moving the aligned visual target and infrared target spot upon the reflective display screen. A matrix detector mounted within the weapon will sense the position of the infrared target spot upon the reflective display screen whenever the marksman fires the weapon, and then supply to a microprocessor computer digital information indicative of the position of the infrared target spot upon the reflective display screen. The microprocessor computer, in turn, processes the digital information so as to determine whether the marksman has scored a hit, a miss, or near miss upon the visual target.

  • Patent number: 4281993
    Abstract: A semiconductor laser alignment device for aiming a laser light beam, broast by a weapon, along an optical light path such that the laser light beam is in alignment with the aiming direction of the weapon at a target which is located a predetermined distance from the weapon. The semiconductor laser alignment device comprises a tubular housing attached to the barrel of the weapon, a laser diode located within the tubular housing for broadcasting the laser light beam, and a projecting lens for collimating the laser light beam broadcast by the laser diode. Zeroing means connected to the laser diode positions the laser diode such that the laser light beam broadcast by the laser diode is in alignment with the line of sight of the weapon.

  • Patent number: 4264309
    Abstract: Projected image target apparatus for gunnery and missile launcher training, comprising a screen onto which a motion picture target is projected from a projector, a light beam projector on the weapon for projecting onto the screen an invisible light beam along the line-of-sight of the weapon, a light beam projector for projecting a visible light beam onto the screen and a system for controlling the projector and light beam projectors. The control system tracks movement of the beam of invisible light and upon firing of the weapon automatically discontinues the tracking and utilizes the position that the invisible beam of light had at the instant of firing the weapon as a datum relative to which the visible light beam is moved automatically in accordance with the ballistic performance of the projectile to simulate trajectory drift and fall of the projectile over the simulated range of the target projected onto the screen.

  • Patent number: 4253249
    Abstract: The effects of any errors in the preliminary tracking of a target, and of any subsequent changes in the velocity of the target, are included in simulated firing of a gun 3, by slewing a laser projector 2 in the simulator for the predicted shell time-of-flight at the rate assessed during the preliminary tracking and then scanning with the laser for hit/miss determination. The slewing is achieved either by having the gun control system slew at the required rate, or by having the gunner continue tracking the target, corrections for deviations from the required rate being automatically applied to the projector.

  • Patent number: 4246705
    Abstract: For initial alignment of a simulator laser-projector with a weapon, the weapon is boresighted on a target, the projector is fitted and the laser beam is scanned stepwise across the target successively along orthogonal axes. The range of steps on each axis for which a return from the target occurs is sensed, and the step corresponding to the median of all the returns taken as the position for which the laser beam is centered on the target. These calculated positions are stored and used as the reference positions during simulated firing of the weapon. The detection of the position of a target for hit/miss determination is achieved with the same scanning and median selection procedure.

  • Patent number: H218
    Abstract: A marksmanship training system has been developed which depends upon the mal levels of infrared radiation emitted from warm-blooded animals, such as humans. An infrared detector is mounted upon a simulated rifle or unloaded real rifle, or other weapon. This detector is mounted with IR lenses in such a way that a positive indication is given when the rifle is pointed at a suitable infrared emitting animal target. A second detector indicates when the trigger of the weapon is pulled. If a trigger pull is detected at a time when an animal infrared signal is present, the system generates an electronic pulse indicating that a target hit has occurred. This pulse may be used to drive a visible or audible signaling device to inform the user of success.
