Max '91: Flare research at the next solar maximum

To address the central scientific questions surrounding solar flares, coordinated observations of electromagnetic radiation and energetic particles must be made from spacecraft, balloons, rockets, and ground-based observatories. A program to enhance capabilities in these areas in preparation for the next solar maximum in 1991 is recommended. The major scientific issues are described, and required observations and coordination of observations and analyses are detailed. A program plan and conceptual budgets are provided

Receiver Noise Factor

International Telemetering Conference Proceedings / May 18-20, 1965 / Sheraton Park Hotel, Washington DCThe Institute of Radio Engineers definition of receiver noise factor is reviewed and adopted for this paper. The definition’s implications are explored. CW-and dispersed-signal source measurement techniques are discussed and the mathematical base for each method is displayed. The quantities which must be measured in each method are pointed out with the respective advantages and disadvantages. It is concluded that the dispersed-signal source measurement technique is simpler than the CW-signal source techniques considered in this paper.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
