Abstract

This paper deals with a breadboard of CO2 laser Doppler rangefinder based upon the "chirp pulse compression" technique, and realized in common by Thomson -CSF and Cilas. It recalls some design considerations derived from properties of heterodyne detection and basic radar theory, then describes the principle and main components of this equipment, and evaluates its overall performance.
