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.
