A system, called the Laser Aim Scoring System, and method for automatically scoring gunner training sessions for simulated laser-guided missile, target engagements using the laser designator without the need for training or tactical rounds are disclosed. In the disclosed invention, a pop-up target and its surrounds are separately monitored for radiations at the laser designator frequency. "Hit" or "Miss" scoring is based on detection of the laser radiation at the laser designator frequency illuminating the appropriate region around or on the target at the appropriate time with respect to a simulated missile launch signal at the start of the training engagement, in accordance with the engagement profile programmed into the scoring computer prior to the start of training. The laser aim scoring system send a signal to lower the pop-up target in response to a "Hit" score, and if desired by the user, also sends a signal to initiate smoke and flash signals from a Hoffman Kill Simulator interfaced with the system. The disclosed invention also sends the appropriate signals at the end of the engagement to reset the target in the upright position so that it is ready for the next engagement. The disclosed invention includes subsystems for transmitting data, video imagery, and control signals between the portion of the system at the target location and the portion of the system at the control tower.

What is claimed is: 1. An active aim scoring system for testing a gunner's ability to designate a pop-up target, near a control tower, with a given laser, at an impact point for a projectile seeking said designated target with a sensor for only the narrow band near infrared radiation from said given laser, comprising: an upper section containing an array of four very sensitive offset detectors focused on the areas in front of, above, to the right of and to the left of said target within 100 meters of the target; a lower section electronically coupled to said upper section containing an on-target detector for said near infrared radiation, and a video camera for detecting visible radiation as well as said near infrared radiation reflected by said target; a computer to record and evaluate output data from all of said detectors; and a modulated transceiver with an antenna to receive test initiation pulses from said tower and transmit test data with evaluation to said tower. 2. An active aim scoring system according to claim 1, further comprising: an electrically fired pyrotechnic device, adjacent said target coupled to said computer, to emit light and smoke in response to a hit pulse; and said computer having a first circuit means to generate a hit pulse in response to a favorable evaluation of said data. 3. An active aim scoring system according to claim 2, wherein said computer includes a second circuit means coupled between said computer and said target to generate a lower target pulse in response to said hit pulse and a raise target pulse in response to said test initiation pulse. 4. A training method for testing a gunner's ability to designate a target, near a control tower, with a given laser, at an impact point for a projectile seeking said designated target with a sensor for only the narrow band near infrared radiation from said given laser, comprising the steps of: placing a substantially two dimensional representation of the target on a mechanism that pops the target upward to a nearly vertical position with respect to the ground plane or downward to a nearly horizontal position in response to an electric signal from the control tower; directing an array of four high sensitivity offset sensors on an upper section of an active aim scoring system for the narrow band radiation toward the target and an area of ground within at least 100 meters therefrom in response to a gunner's cue signal; directing a video camera and a low sensitivity sensor on an lower section of said active aim scoring system for the narrow band radiation only toward the space occupied by the target, when the nearly vertical position, in response to the same cue signal; loading a designation program into a first computer that defines output signal threshold levels of the sensors as a function of time for an ideal laser illumination of the area around the target and finally the target is illuminated long enough to avoid enemy detectors and to insure proper missile impact; transporting the gunner and the given laser toward and within missile range of the target; generating the cue signal from the gunner to the control tower to indicate a launch time for the missile; generating the signal from the control tower to the target in response to the cue signal; feeding the actual sensor outputs to the first computer; generating a score, in the first computer, based on the actual sensor outputs as a function of time as compared to the required sensor outputs; computing the time of expected missile impact at the target from the launch time in the first computer; and generating the electric signal in the control tower, if the score exceeds a preselected hit threshold. 5. A training method according to claim 4, further comprising the steps of: generating an electric hit signal in the first computer if the electric signal generated in the control tower has been generated at the time of impact; transmitting the hit signal, if present, to the target mechanism to lower the target in the event that a hit is scored; and transmitting the hit signal, if present, to a hit simulator in the form of an electrical squib, whereby the hit signal fires the squib to generate smoke and light signals visible for the gunner and anyone in the control tower. 6. A training method according to claim 5, further comprising the steps of: storing the output signal from the video camera, as well as the computer and the values of the actual sensor outputs in a second computer in the control tower; clearing the first computer for a new test; and generating an electric signal to the target mechanism to raise the target if the hit signals were generated in the control tower resulting in lowering the target.
