摘要：
We have measured the power spectra of surface waves generated by an unstable circular hydraulic jump. If the waves are scattered, the spectra show interference patterns which, using semiclassical approximations, have a simple interpretation as interfering geometric orbits. We also measure the jump radius as a function of various parameters, and find reasonable agreement with theory.
