Abstract

Abstract: It is found that distortions are produced for Maxwellian distribution of the ion velocity distribution due to a large convection electric field appearing in the high latitude region. In this paper, an analytical form of Non-Maxwellian ion velocity distribution in the line-of-sight direction is used. According to the incoherent scattering theory, the incoherent scattering spectral is derived and computed. This study shows that the analytical Non-Maxwellian distribution function can simplify the calculation of the incoherent scattering spectral and improve the velocity of computing incoherent scattering spectra.

Key words: incoherent radar spectra, non-Maxwellian distribution, ion velocity distribution function
