The Calculated Performance of Some Radar and Transmissometer Systems in Rain and Fog at 35, 94, 140 and 240 GHz. Volume 1.
Abstract
The effects of rain and fog are examined for three transmissometer and three radar systems: double-ended (direct path) with square-wave modulation and square-law detector; single-ended (folded path) with square-wave modulation and square-law detection, single-ended CW with quadrature receiver, single-ended pulsed with post-detection pulse integration, single-ended pulsed with quadrature receiver, and single-ended with linear FM pulse compression. Computer algorithms were developed to find the probability of detection as a function of range for the radar systems, and the signal-to-noise ratio as a function of range for the transmissometer systems. These algorithms are used recursively to determine the range at which specified performance is attained as a function of rain rate of fog liquid water content. Calculated results are presented for exponential drop-size distributions; provision has been made for the extension to other distributions. Volume I contains the theory and results; computer code listings and directions for use of the codes are given in Volume II. (Author)
