Abstract

A new approach to the Army Tactical Engagement Simulation System (TESS) is proposed to increase the link reliability, increase range, and increase the amount of data that can be transferred. The new technology uses both laser sources and detectors with improved propagation properties that meet eye-safety requirements, and meet the cost requirements for TESS laser systems. The new technology offers the prospect of increasing both the laser power and link efficiency by overcoming scintillation and fading problems due to atmospheric turbulence characteristic of battlefield training. Efficiency and the amount of data transferred under engagement pairing may both be increased by utilizing new coding schemes with the lasers and detectors, along with improved digital signal processing. Increased range while retaining important information related to roll-off also appears possible. New techniques to extend battery lifetime will be explored, along with detailed simulation of the expected results and component testing. If successful, field-testing of the new technology is anticipated in a Phase II effort.
