Abstract

Night vision system developments have played a crucial role in the warfighting tactics of our armed forces. The ability to see and fight at night have given our military an unprecedented advantage. Passive night vision systems, Forward Looking InfraRed sensors and Night Vision Goggles, have provided the capability to do daytime air combat tactics at night in tactical jet aircraft. Despite opening a whole new way of fighting the enemy, the existing night vision systems have deficiencies that limit their utility.

This paper comments on simple night vision theory, discusses the history of night vision devices, presents the deficiencies and enhancing qualities of existing night vision systems, and outlines basic requirements and specifications for a new night vision design for tactical jets. The proposed conceptual design utilizes the evolving technologies in digital Forward Looking InfraRed (FLIR) systems, advanced image intensifiers, sensor fusion, high speed computer processing, accurate helmet tracking systems and advanced helmet mounted displays. The critical aspect of the design is the integration of two separate sensors through sensor fusion algorithms and high speed processing to provide one improved dynamic image. The proposed night vision design of a forward fuselage mounted dual sensor turret linked to an advanced helmet mounted display through an accurate helmet tracking system should meet all the future night vision requirements.

Much of the information to rate the deficiencies and enhancing qualities of the existing systems is based on personal flight test of the night vision systems in the F/A-18 C/D, F-15E, and AH-64 aircraft. This thesis and all reference material listed are unclassified. In addition, the proposed conceptual design does not compromise company private information.
