Transversely excited atmospheric CO(2) laser radar with heterodyne detection.
Ranging has been demonstrated with an experimental laser range finder employing a hybrid TEA CO(2) 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 CO(2) laser transmitters in optical radar systems capable of detecting and tracking high speed targets is briefly discussed.
