Paper Abstract

A 10. 6 micron eyesafe laser rangefinder (LRF) has been designed for use on the M1A2 tank. Prototypes have been fabricated and extensive engineering tests have been performed. The unit is characterized by extreme optomechanical rigidity a high brightness projected LED array highly modular packaging and advanced built-in test capability for ease of I-level maintainability. Several LRFs have been delivered to date for testing under field conditions to verify performance. Reliable range returns have been demonstrated against canvas targets at ranges to 4500 meters (the length of the range) over swampy terrain under conditions of rain during the summer in Florida. Likewise reliable returns have been demonstrated against targets of opportunity at ranges to 5700 meters under conditions of rain during mid-latitude winter conditions. Required range sensitivity has been demonstrated by ranging against the common module FUR and by numerous attenuation filter tests. Trends in LIDAR performance against theoretical predictions are discussed. Large sample size test methods are required to detect low frequency of occurrence phenomena and to control their rate.
