Abstract

Automatic Fixed and Mobile Laser Range and Tracking Systems utilizing eye-safe gallium arsenide injection diode lasers provide improved range accuracies and angle position data of high and low speed ground and air targets. The system can utilize small cooperative targets to ranges of 7-10 Km and non-coopera-tive targets to ranges using low power, high pulse rate gallium arsenide transmitters in excess of 1.5 Km. The systems are eye-safe. The high data rate associated with pulse rates up to 4 Khz and improved accuracy measurements, 15 cm single shot, 2 cm averaged, permits improved tracking and velocity data of high speed targets. For applications requiring extreme single shot accuracy for high speed tracking, special 1/2 nanosecond counters can be utilized providing 8 cm accuracy on a single shot basis. The paper describes the trade-offs associated with the electro-optical design, such as beamwidth, field-of-view, pulse-rate, computer control, tracking and ranging requirements and range accuracy analysis.
