Target and atmospheric influence on coherent CO2 laser radar performance.
Experimentally verified signal amplitude distributions from a coherent CO2 laser radar have been used to derive radar performance for atmospheric remote sensing and hard target detection. Different target types include man-made diffuse, semirough, and glint targets as well as terrain backgrounds. The results, given as gas concentration accuracy and probability of detection, respectively, show the importance of including beam wandering especially for glint targets. It is shown how Doppler sensing and range gating improve target detection against terrain background.
