Radio noise near the earth in the 1–30 MHz frequency range

Part of the Lecture Notes in Physics book series (LNP, volume 362)


Terrestrial radio interference presents a serious problem for sensitive low-frequency radio observations from space near the Earth. The interference is both narrow band and broad band. Several satelites and planetary probes have carried radio astronomy experiments so a moderate amount of information is available concerning the noise radiation from the Earth. The region of space within 100 RE of the Earth is quite a hostile environment for any radio astronomy experiment. Observations up to 10 MHz employing ionospheric shielding may be possible from satellite altitudes on the sunlit side of the Earth near solar maximum. Observations above 10 MHz should be made from the surface of the Earth or from the Moon.
