Pulsed Laser Ranging Techniques at 1.06 and 10.6 Micrometers

Abstract

Heterodyne and direct detection pulsed laser range finders at both 1. 06 and 10.6 micrometers are compared. The application involves a transmitter/ receiver at ground level ranging on unresolved high velocity projectiles which appear a few degrees above the horizon at ranges up to 10 km. The analysis includes effects of backgrounds, atmospheric turbulence, atmospheric attenuation and target surface characteristics. Available and projected CO2 and Nd:YAG laser power levels are assessed to determine expected operating ranges for each system.
