Abstract : Mathematical simulation was used to compare candidate systems for Slant Visual Range/Approach Light Contact Height measuring equipment. Inputs to the simulation include response of the human visual system, typical atmospheric data, atmospheric scattering data, and characteristics of each candidate system. The candidate systems modeled were the transmissometerceilometer, Videograph B, two backscatter lidar systems, and a forward scatter laser system. Other systems were studied but eliminated for various reasons before simulation. (Author)
