The experimental observation of acoustic ray deflection by aircraft wake vortices was reported by Burnham et al. (ibid., vol.52, no.1, p.431 (1972)). In the present paper the theoretical basis for the observations is given, a variety of vortex core models are considered, the capabilities of a pulsed acoustic vortex tracking system are discussed, and the effects of timing errors on tracking accuracy are derived. The properties of a tracking system based on refractive scattering and the properties of a system using incoherent acoustic scattering from turbulence are compared.
