Abstract:

Work conducted by Texas Instruments Incorporated from November 1966 through January 1967 under the Cumberland Plateau Observatory CPO contract is reviewed in this quarterly report. Effort, during this quarter have been directed toward observatory operations, hardware construction and on-line implementation, and Dallas-based supporting research. Observatory operations and additional data on the coefficient loss problem which previously existed in the MCF processor are summarized in Section II. In addition to the rapid-stop monitor for detecting marginal input power, modifications to the processor grounding system were necessary to eliminate entirely the problem of coefficient losses. Research activities, including ambient noise studies, visual data display improvement and MCF processor evaluation, are reviewed in Section III. Data are presented which demonstrate the continued time-stationarity of the ambient noise field over a 2-yr period, thus indicating that, in at least general terms, MCF operators developed under previous efforts are appropriate for present application in the MCF processor. Design, construction and installation of the auxiliary detection and identification processor were completed on 30 December. A description of the system and a discussion of the on-line implementation and operating parameters are presented in Section IV. Also included is a discussion of the evaluation procedures and goals and an outline of the supporting Dallas-based research.
