Abstract:

The characteristics of a signal data converter (SDC) are developed with application to airport visibility measuring systems. The SDC is discussed in the context of an evolutionary growth of the visibility measuring system stemming from the present FAA RVR measuring technique. A new SDC will be employed which will use state-of-the-art concepts and will be capable of handling future visibility measuring systems outputs to provide more comprehensive visibility information and display. Included in these out puts will be simultaneous signals from as many as nine ways. In addition, round illuminance sensors will provide more background discrimination than the present day-night switch. Finally, the system will be expected to handle inputs from several kinds of target lights and to calculate and output for display several specialized visibility values (RVR, SVR, TVR). The SDC will be capable of modular expansion such that the capability for such future tasks will be available.
