Paper Abstract

Trex has developed two innovative MWIR tracking systems, the Rapid Optical Beam Steering (ROBS) system and the Fast InfraRed Sniper Tracker (FIRST). ROBS was developed by Trex in the mid 1980’s for BMDO and the Navy as a prototype 0.5 meter aperture, wide-angle, multiple target detection, tracking, and imaging system with laser ranging. The smaller FIRST system was developed in the mid 1990’s by Trex for DARPA to acquire and track small caliber bullets. Both systems utilize innovative fast steering methods for achieving very high acceleration rates, ~ 1,000 radians/sec2 for ROBS and ~ 40,000 radians/sec2 for the FIRST system. Each can provide high precision 3D tracking over a large field of regard and both have been demonstrated in field tests. Presently the capabilities of these systems are being expanded. A newer version of the ROBS, 3DATA, is being completed which will provide a capability to precisely track in three dimensions up to 20 targets per second, simultaneously. In addition, an upgraded FIRST system is being designed and built which will handle multiple slow targets in addition to the faster bullets.
