Effect of Weather at Hannover,Federal Republic of Germany,on Performance of Electrooptical Imaging Systems. Part 1. Theory,Methodology,and Data Base.

摘要

This paper examines the effect of weather on the probability of electrooptical detection of tanks at various ranges. The paper employs actual weather data recorded hourly at Hannover, Federal Republic of Germany, for a full year (1970) and a mathematical model of the electro-optical detection/recognition process developed by R.L. Sendall and L.M. Biberman from the perceived signal-to-noise concept of F.A. Rosell. The mathematical model makes use of a slightly modified version of the LOWTRAN 3 atmospheric transmittance model developed by the Air Force Geophysics Laboratory. The results show a wide variability in the probability of detection caused by wide and frequent variations in the weather. (Author)
