摘要：

Previous studies have shown that quasi-monochromatic waves in the frequency range 1-15 Hz are usually observed upstream of the ramp of supercritical quasi-perpendicular shocks. A number of models have been proposed to explain the origin of these waves. In order to differentiate between these models, one has to determine both the observed frequencies and also wave vectors of the measured waves. The present paper is devoted to the determination of the dispersion relation w((k) over right arrow) of these waves, using simultaneous data from AMPTE UKS and AMPTE IRM. (C) 1997 COSPAR.
