Исследование ионосферы Земли сигналами геосинхронных спутников в Ku-диапазоне

Abstract

Рассмотрена методика построения приемного тракта устройства для приема служебных сигналов геосинхронных спутников в Ku-диапазоне для экспериментального исследования неоднородностей верхних слоев атмосферы Земли. Приведены возможности использования полученных результатов измерений для изучения процессов распространения радиоволн.

This paper describes the design and development of a digital satellite beacon receiver for the different kinds of atmospheric researches. Satellite beacons are frequently available to assist pointing large antennas. Software Defined Radio (SDR) as a terminal device gives possibility to make a cheap tuner for receiving the CW (continuous wave) 3 cm length radio wave which is usually used as the beacon frequency. Some energy equations and formulas help to understand the readers the basic energy performance of the GSO satellite communication. There are practical recommendations how to operate the LNB (low noise block) to achieve the optimal result. The practical circuit has been tested and might be successfully replicated The article gives some ideas for scientific and technical application of the GSO satellite link for the measurement of microwave propagation.
