Night vision goggle aided flight simulation system and method

DETAILED DESCRIPTION It is therefore the object of the invention to provide an system and technique for night vision goggle aided flight simulation.
According to the invention, a night vision goggle aided flight simulation technique and system utilizes database sources so that a flight simulator operator viewing a simulator generated scene with night vision goggles simulation of night vision goggle aided flight.
Database sources include: goggle, illumination source, background, targets, relative humidity, range to the most distant target, filters, and windscreens.
These sources may also be selected options chosen by the user.
At least one look-up table is generated based on the input variables which is utilized for the scene generation contrast.
The contrasted scene is then displayed by a display system with sufficient intrascene dynamic range so that an approximate simulation of night vision goggle aided flight is achieved.
If the display system is a cathode ray tube (CRT) display which cannot produce sufficient intrascene dynamic range, a neutral density filter may be placed over the CRT display or over the night vision goggle lens.
