Abstract : The primary purpose of this program was to investigate reflected signals from atmospheric aerosols in order to ascertain their strength and to determine whether or not they were distinguishable from signals reflected from solid targets. The range degradation of the system due to the presence of various aerosol size distributions was also to be determined. Tests conducted during the program included system stability, receiver linearity, and target reflectivities. In addition, transmission, aerosol, and backscatter measurements were taken. Results show that, for the system tested, backscatter from natural aerosols should be only a marginal problem. However, for a system where the field of view is large compared to size of the target, detectable returns from aerosols might be expected, so that each new configuration should be examined for a possible backscattered signal.
