Abstract

Ranging has been demonstrated with an experimental laser range finder employing a hybrid TEA CO₂ laser transmitter and a heterodyne detection receiver. A description of the system, including its operating principles and performance characteristics, is presented. Ranging results are given to 5 km on targets with previously measured characteristics and to 32 km on natural targets. The application of TEA CO₂ laser transmitters in optical radar systems capable of detecting and tracking high speed targets is briefly discussed.
