THE NRL MICROWAVE SPACE RESEARCH FACILITY: COMPUTER SYSTEM HARDWARE FOR DATA ACQUISITION AND CONTROL OF THE 60-FT X-BAND ANTENNA.
Abstract
To provide precise control of the fully steerable, 60-ft X-band antenna at the Naval Research Laboratory (NRL) Waldorf Microwave Space Research Facility (MSRF), a computer-oriented control system has been developed to control pointing of the antenna. The system has provisions for real-time data acquisition and processing for the control of experiments as well as for the display of antenna-related information such as antenna position, tracking object range, object look angles, and doppler frequency shift. Control equipment has been developed by NRL to provide the interface between the antenna system and the associated Control Data Corporation 924A general-purpose digital computer system. All control actions of the real-time system interface with the computer are transmitted to the desired equipment through logic circuits in the interface system. The computer system has been provided with a unique logic system for data acquisition and display. This capability allows the computer to acquire and convert analog data to digital form in real time via the interface system so that real-time processing may be used to modify experimental parameters. Alternatively, the acquired digital data may be stored for later processing in other computer systems. (Author)
