Study of the Performance of Airborne Laser Radar Systems and Techniques

摘要

Helium-neon, neodymium (YAG), and CO2 laser radar systems are reviewed. Laser properties and hazards are discussed. Modulation techniques; optical detectors; beam steering; and signal processing are considered. System losses; atmospheric propagation; noise sources; and optical clutter are described. Laser radar range equations are analyzed. Applications including ranging, airborne surveillance and reconnaissance, wind velocity measurement, terrain following, and obstacle avoidance are treated.
