LASER DOPPLER RADAR SYSTEM CALIBRATION AND RAINFALL ATTENUATION MEASUREMENTS

The atmospheric attenuation and backscatter coefficients have been measured at the 10.6-micrometers wavelength of the CO2 laser in rainstorms. Data are presented to show the increase in attenuation coefficient with rainfall rate. Backscatter coefficients in rain and clear air are also presented. Data were collected on a 460-meter test range at Sudbury, Massachusetts. The experimental results can be used to evaluate the performance capabilities of CO2 coherent laser systems for making atmospheric velocity measurements. (Author)
