Abstract
This paper describes an experimental system of representing the reading on an altimeter in the form of a digital code, and controlling the standard I.C.A.O. secondary surveillance radar transponder to give a corresponding pulse pattern.
Different code arrangements are examined and their capacity noted. A possible use of the system in collision avoidance is suggested for use outside areas of close air traffic control. This use would require little additional equipment.
