Abstract
The signal-to-noise ratio of system is a impotant parameter for the CO2 coherent laser radar. In order to improve the signal-to-noise ratio of system the matched filter, interlock processor and frame-average are extensive applied(1). The methods of improving signal-to-noise ratio of the system by computer are digital-filter, accumulated average, interlock operation and so on(2),(3). At first, the backwave signal from target has been analysed, then the coast average method has been used in signal processing. We have developed a computer system for improved signal to noies ratio and it has been increased by 60db.
