Apparatus for and method of detecting a reflector within a medium
First Claim
1. An apparatus for detecting a reflector within a medium, comprising at least one transmission device for sequentially focusing energy towards a selected one of a plurality of volumes of the medium, and a reception device for receiving energy reflected from the selected volume of the medium, and having an adjustable frequency of the energy so as to set the wavelength thereof in the medium to a predetermined wavelength.

Abstract
An apparatus is provided in which a phased transmitting array (21) is arranged to irradiate a selected voxel within a search volume. Energy reflected from the voxel is received by a further antenna and the signals received from a plurality of voxels are analysed to search for reflectors or discontinuities within the search space.
