Ionospheric Heating by Obliquely Transmitted High Power Radio Waves

Abstract

Anisotropic effects of ionospheric irregularities on Faraday polarization fluctuations have been investigated. It was found that sheet like irregularities are more effective than rod like irregularities in causing Faraday polarization fluctuations. Measurement of the fluctuation spectrum may be used to diagnose ionospheric irregularities. Nonlinear scattering of HF waves by ionospheric irregularities has also been investigated. It was shown that HF ionospheric heating can be further enhanced by nonlinear scattering of VLF waves. Artificial spread F caused by ionospheric heating with either vertically or obliquely incident high power HF waves has been investigated by ray-tracing simulation codes.
