RADIO WAVE ENVIRONMENTAL OBSERVATION DEVICE AND RADIO WAVE ENVIRONMENTAL OBSERVATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio wave environmental observation device for observing the radio wave environment of a stratosphere that is a target, and to provide a radio wave environmental observation method.;SOLUTION: The radio wave environmental observation device 3 and a GPS sonde 4 float by a balloon 2. Radio waves, received by an observation antenna 7, pass respective band-pass filters 10 for each frequency band, and the intensity of the electric waves of each frequency band is measured by respective radio wave intensity measuring devices 11. Measured radio wave intensity signals are output to an encoder 25 from each voltage converter 12. The detected position signal, measured temperature signal, measured humidity signal and measured atmospheric pressure signal are output to the encoder 25 from a GPS-receiving part 21, a temperature sensor 22, a humidity sensor 23 and an atmospheric pressure sensor 24, respectively. The measured radio wave intensity signal, the detected position signal, the measured temperature signal, the measured humidity signal and the measured atmospheric pressure signal are multiplexed by the encoder 25 and are output to a transmitter 26 and are transmitted from a transmission antenna 8.;COPYRIGHT: (C)2006,JPO&NCIPI
