摘要

Results of test and evaluation of two laser ceilometers,by AFCRL,are presented and discussed. A test program was initiated in 1970to evaluate the applicability of lasers to determine cloud height for navigational guidance. The approach was to study the characteristics of laser ceilometers,and to determine how the cloud return data obtained from these systems compare with data generated by the standard Air Force rotating beam ceilometer (RBC). Two laser ceilometers were tested. One was a ruby system manufactured by ASEA of Sweden,and the other was a prototype eye-safe erbium lidar developed by the American Optical Corporation, Framingham,Massachusetts. Data comparisons show that lidars produce the same type of cloud height information as the RBC. The lidars tested have a significantly greater ranging capability than the RBC and provide more cloud structure information. It was concluded that lidars are potentially superior to the standard rotating beam ceilometer as cloud height measuring devices. (Author)
