CO 2 dial transmitter/receiver noise characterization and related correlated noise issues

Abstract

Our approach concerning the development ofhard target returnCO2 DIAL transmitter/receiver systems is two phased: i) through analysis and experiment, develop a fundamental understanding ofthe transmitter/receiver physics specific to DIAL systems and ii) apply these fundamentals in the development of optimal performance DIAL transmitter/receiver systems.We present our progress and results towards these objectives with the following topics addressed: A general overview of the DIAL transmitter/receiver system characterization effort with a focus on transceiver noise processes. The effects of correlated noise on DIAL performance, especially those effecting statistical convergence over long sample structures, is introduced. And, preliminary measurements of a low-noise, "white" receiver prototype are presented. I Detector Signal Ii and [Processing J Amplifier _____________________________ Range Signal Figure 1.
