Download or read book Improvement in Short Wave Fade Detection written by David N. Gaunt and published by . This book was released on 1975 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain types of solar emission produce changes in the ionosphere (identified by Short Wave Fades (SWF)) that adversely affect the efficiency of radio communications. The detection of SWF is in principle a relatively simple approach to the measurement of ionospheric changes and the causative solar emissions. In practice, however, numerous factors may compromise the value of SWF data. An improved Short Wave Fade detection system is described which by techniques of frequency sweeping, reduction of unwanted signals by clipping, and enhancement of desired information by integration makes reliable, quantitative, absorption, and spectral information possible.
