Further Investigations of the Amplitude Variations of Downcoming Wireless Waves

摘要: Experiments are described for measuring the lateral deviation of wireless waves after reflection from E and F regions ionosphere. It was found that greatest observed, 20° or more, due to e region, least, about 0·5°, normal region in case a distant transmitter.The time variation amplitude reflected wave be consistent with random scattering at ionosphere.In theoretical discussion it is shown changing horizontal irregularities, ion clouds, very important cause fading. Values calculated average fading periods which would result winds neighbourhood known exist other evidence. These agree observed inferred
