On External Radio Emission from the Earth's Outer Atmosphere

Abstract

The possibility is considered that cyclotron radiation, generated by fast bunched electrons in the Earth's outer atmosphere, may be observable outside the geomagnetic field. It is shown that the intensity and other properties of such external radiation may be deduced from the known characteristics of v.1.f. hooks. It appears likely that the radiation will occur as short bursts in the frequency range from 200 to 1000 kc/s. The total radiated power may be from 1 to 1000 W, depending on the electron energy.
