Abstract

1,144,345. Radio position finding. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 16 May, 1966 [28 May, 1965], No. 22713/65. Heading H4D. The position of a material interface, e.g. that between the atmosphere and a column of water, is determined by immersing a transmission line 4 in the material, of such a type that the material becomes the dielectric of the line, and an impedance discontinuity appears at the interface. As shown the line is an airspaced coaxial cable, holes allowing the material to pass into its interior. Thus by passing a pulse down the line, the interface reveals itself by a reflection, the depth of the interface being given by the time lapse between the transmission of the pulse and its echo. The echo is displayed on an A-type C.R.T. The transmission line may, alternatively, comprise two parallel wires, or the outer conductor of the line, when coaxial, may be the metal container of the material.
