Author: Michael Kolawole
Publisher: Elsevier
ISBN: 0080515622
Category : Technology & Engineering
Languages : en
Pages : 392
Book Description
As well as being fully up-to-date, this book provides wider subject coverage than many other radar books. The inclusion of a chapter on Skywave Radar, and full consideration of HF / OTH issues makes this book especially relevant for communications engineers and the defence sector.* Explains key theory and mathematics from square one, using case studies where relevant* Designed so that mathematical sections can be skipped with no loss of continuity by those needing only a qualitative understanding* Theoretical content, presented alongside applications, and working examples, make the book suitable to students or others new to the subject as well as a professional reference

HF Sky-wave Measurements and Predictions

ISBN:
Category : Ionospheric radio wave propagation
Languages : en
Pages : 100
Book Description
Measurements for the month of April 1969 were made on a 2.666-MHz east-west path between Long Branch, Illinois, and Boulder, Colorado, to validate current ESSA/ITS prediction programs. After the difference between the measured observations and the computer calculations had been determined, additional path calculations centered about the Boulder receiving site were made to identify potential interfering sources. Point-to-point calculations along quadrature radials were used, with the range being incremented five times along each radial between the limits of 500 and 5000 km. The analysis determines the required transmitter power to produce a CW signal via the predominant mode which is 90 percent reliable and 12 dB above the controlling noise (atmospheric, man-made, galactic, or a combination). The averaged night values of required transmitter power including an 8-dB correction factor found from the measured observations, are tabulated by month as a function of both the bearing and range.
