Summary

A propagating wave is described by its frequency and its wave vector. With a few rare exceptions all spacecraft measurements of plasma waves were designed to characterize wave frequency only. In this paper we discuss a series of experiments designed to characterize wave vector and wave frequency. The basic technique is to measure the phase shift between spaced sensors. The phase shift is a measure of the projection of a wave vector onto the axis of an interferometer. Two examples of interferometer data are presented. The first example is of plasma waves within a transverse ion acceleration region and the second example is of spatial density irregularities.
