Download or read book Techniques for Computing Refraction of Radio Waves in the Troposphere written by E. J. Dutton and published by . This book was released on 1961 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight methods of computing atmospheric refraction of radio rays are discussed with appropriate theoretical background. These methods are: (1) The high-angle, or astronomical, refraction case; (2) The statistical method; (3) The low-angle, or terrestrial, refraction case (Schulkin's method); (4) The four-thirds earth model; (5) The exponential model; (6) The initial gradient correction method; (7) The departures-from-normal method; (8) A graphical method (Weisbrod's and Anderson's method). Sample computations are included for each of the above methods.

Available in PDF, EPUB and Kindle. Book excerpt: An atmospheric duct is defined as occurring when geometrical optics indicates that a radio ray passing upwards through the atmosphere is sufficiently refracted that it travels parallel to the earth's surface. Maximum observed incidence of ducts was determined to be 13%, 10%, and 5% by analysis of three to five years of radiosonde data for a tropical, temperate, and arctic location, respectively. Annual maxima are observed in the winter for the arctic and summer for the tropics. Arctic ducts arise from ground based temperature inversions with the ground temperature less than -25 C; temperate zone ducts arise from radiation inversions and accompanying humidity lapse; while tropical ducts occur with slight temperature and humidity lapses when the surface temperature is 30°C and greater. The mean initial elevation angle of a radio ray trapped by these ducts is found to be about 3 mr, with the maximum value about 5. 8 mr. The steepest gradient of N observed is -420 N units/km. Observed ducts trap radio-waves of frequency 2: 1 kMc at all locations for at least 50% of the time. Fading regions arising from abnormal defocusing of radio- rays passing from an elevated antenna down through the duct to a ground-based receiver are analyzed. The horizontal extent of these regions is determined for the same arctic, tropic, and temperate conditions given above.
