Abstract

A CO₂-laser heterodyne system consisting of a CO₂ TEA laser transmitter and a CO₂ cw laser local oscillator with a fast data system is used to measure simultaneously range and velocity of solid targets. The basic properties of such a system and the accuracies for range measurements were investigated. Further, heterodyne experiments without oscillation of the pulses but with the full advantages of heterodyne detection were carried out.
