Abstract
Abstract A gun simulator system which is capable of safely simulating any airborne gun. The simulation takes into account not only aircraft approach angle but also preselected range and bullet trajectory. In so doing, the gun simulator system records hits both on the ground and in the aircraft for each pass. In addition, the simulator system is readily adaptable for use with already existing simulator programs.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
210 words
A gun simulator system comprising a source of electromagnetic radiation energy at a first location for transmitting a plurality of electromagnetic pulses, a target at a second location, means optically aligned with said plurality of pulses for continually varying the angle of output of said pulses, means optically aligned with said plurality of pulses for directing a substantial portion of all of said electromagnetic radiation of each of said pulses in the direction of said target and the remainder of said electromagnetic radiation of each of said pulses in another direction indicative of the start of each of said pulses, means on said target for reflecting said pulses, means optically aligned with said target for receiving said reflected pulses, computer means operably connected between said electromagnetic source and said receiving means for comparing the time interval between the start of each of said pulses and the reception of the same pulse in order to determine whether said pulse is received within a preselected time interval thereby establishing range information and for comparing said range information with preselected trajectory information corresponding to said range information, whereby the output of said computer means provides a signal indicative of whether the output of said gun fired at said target would strike said target.
Claim 2
Dependent Claim
210 words
A gun simulator system comprising a source of electromagnetic radiation energy at a first location for transmitting a plurality of electromagnetic pulses, a target at a second location, means optically aligned with said plurality of pulses for continually varying the angle of output of said pulses, means optically aligned with said plurality of pulses for directing a substantial portion of all of said electromagnetic radiation of each of said pulses in the direction of said target and the remainder of said electromagnetic radiation of each of said pulses in another direction indicative of the start of each of said pulses, means on said target for reflecting said pulses, means optically aligned with said target for receiving said reflected pulses, computer means operably connected between said electromagnetic source and said receiving means for comparing the time interval between the start of each of said pulses and the reception of the same pulse in order to determine whether said pulse is received within a preselected time interval thereby establishing range information and for comparing said range information with preselected trajectory information corresponding to said range information, whereby the output of said computer means provides a signal indicative of whether the output of said gun fired at said target would strike said target.
Claim 3
Dependent Claim
77 words
A gun simulator system as defined in claim 1 wherein said computer means provides a first signal indicative of one of said pulses being received by said receiving means and a second signal indicative of said trajectory information, said electromagnetic radiation source receiving said first signal and emitting a distinct pulse of electromagnetic radiation, and said output angle varying means receiving said second signal and establishing the angle of output of said distinct pulse in accordance therewith.
Claim 4
Dependent Claim
25 words
A gun simulator system as defined in claim 2 wherein said electromagnetic radiation source is a laser and said emitted pulses of radiation are eyesafe.
Claim 5
Dependent Claim
19 words
A gun simulator system as defined in claim 3 wherein said output angle varying means is an acousto-optical modulator.
Claim 6
Dependent Claim
18 words
A gun simulator system as defined in claim 4 wherein electromagnetic energy directing means is a beam splitter.
Claim 7
Dependent Claim
30 words
A gun simulator system as defined in claim 5 wherein said reflecting means on said target provides a signal when struck only by a preselected one of said distinct pulses.
Claim 8
Dependent Claim
45 words
A gun simulator system as defined in claim 6 wherein said remainder of said electromagnetic radiation of each of said pulses indicative of the start of each of said pulses amounts to approximately 3% of all of said electromagnetic radiation of each of said pulses.
