A shuttle‐pulse technique for simultaneous measurement of the attenuation and bistatic scatter of millimeter waves is described. Measurements were obtained using a propagation path through rain of only a few meters; therefore, the rainfall statistics can be considered constant within the sample volume. Absorption data resulting from this experiment show a disagreement with theory similar to that previously reported. A “total bistatic scatter coefficient” for rain is defined, and the technique of using a shuttle pulse for its measurement is discussed.
