Automated Visibility Measurements with a Horizon Scanning Imager. Volume 1. Technical Discussion
Johnson, R. W. | Karr, M. E. | Varah, J. R.
This two volume report describes the continued development and enhancement of an electro-optical system designed for the automatic acquisition and archival of local horizon imagery specifically tailored to the determination and assessment of daytime sector visibilities and subsequently their spatial and temporal variables. Volume 1 describes the extension of the system's capabilities into the nighttime regime and presents preliminary night imagery suitable for use in the identification of distant lights as visible targets. Techniques for improving daytime target selection and characterization are also discussed. Volume 2 contains engineering documentation, software documentation, preliminary operations manual and preliminary field test plan. (Author)Show more [+] Less [-]
