A scatter-signal analyser

The paper describes a scatter signal analyser which enables level time-structure measurements to be made on scatter propagation signals. The analyser consists of several different units, the most important which is a level comparator of the sampling type whose speed response is sufficient to deal with the highest fading rates anticipated. The various units may be interconnected in different ways, and paper explains how the analyser may be used to measure amplitude distributions, median aerial gains, signal auto- and cross-correlations, fading rates and, in some circumstances, error rates.
