Abstract:

Five systems for transmission measurements at 94 GHz were compared. The systems are two-ended with square-law detector, single-ended with square-law detector, single-ended with chopped signal transmission and quadrature receiver, single-ended with pulsed source and incoherent integration, and single-ended with pulsed source and quadrature receiver. The signal-to-noise ratio expressions for the output of each receiver are given. The signal-to-noise ratios are presented as functions of range, and the ranges corresponding to SN10 are plotted versus specific attenuation. The computer programs that generate these curves for each system are also given. Expressions and computer subroutines to calculate the attenuation due to rain are included. The two-ended system gives the best performance. Of the single-ended systems, which are more convenient to use, the one with a quadrature receiver gives the best results. Author
