Abstract:

The report describes a proposed design of an altimeter system to give reentry altitude data and height-of-burst information. The intended application of the proposed system requires a missile-borne altimeter that is similar to the pulse-radar ranging device developed by HDL for the Pershing missile. The associated data acquisition station DAS must be capable of operating either ground based or airborne. Operation of the system proposed requires simply a transmitter and transponder contained in the reentry vehicle and a DAS located in either an airplane or surface station. The altitude data are recorded in digital form, together with an analog record of TM data. The recorded information is processed later by a computer. The design is based on a 40-ft system accuracy requirement and not on component limitation. Feasibility of the design concept has been proved in five flights under Pershing missile environment. The accuracy of the Pershing altimeter was approximately 15 ft. A detailed description of the proposed altimeter design and its theory of operation are reported. Author
