This paper describes the design of a coherent imaging CO2 laser radar, based upon the use of a continuous wave, single mode CO2 laser and the "chirp" pulse compression technique. This experimental breadboard generates three independent images of a given scene, respectively representative of the range, radial velocity and reflectance (at 10,6 μ) for each of its resolution spots. It has been tested outside and some typical images are pre-sented here, demonstrating the high Doppler sensitivity and range accuracy of pulse com-pression techniques applied to coherent CO2 laser systems.
