Development of a Forward Scatter Wideband Atmospheric Probing Technique.
Abstract
The report is concerned with the study, design, and fabrication of a modulator/demodulator suitable for probing and analyzing a forward scatter path at 15 GHz to determine clear air turbulence (CAT) in the common volume. The equipment is called wideband prober-analyzer. The prober part at the transmitter consists of a Gunn Source and a modulator generating a biphase signal switched at the maximum rate of 12.5 Mbps. The analyzer part at the receiver site performas on-line processing to permit real-time measurement of forward-scattered power, Doppler offset and Doppler RMS spread as a function of signal delay. Direct display of amplitude and drequency information is provided. (Author)
