Pulsed Laser Ranging Techniques at 1.06and 10.6Micrometers.

摘要

Heterodyne and direct detection pulsed laser range finders at both 1.06and 10.6micrometers 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 10km. The analysis includes effects of backgraounds,atmospheric turbulence,atmospheric attenuation and target surface characteristics. Available and projected CO2and Nd:YAG laser power levels are assessed to determine expected operating ranges for each system. (Author)
