高纬电离层离子速度分布函数及其非相干散射谱
The velocity distribution function and incoherent scattering spectra of ion in high-latitude ionosphere
摘要
Abstract
Considering the relatively strong electric field and small collision frequency between ion and neutral in the high-latitude ionosphere ,the integral solution of the non-Maxwellian ion velocity distribu-tion function for the relaxation collision model is simplified ,the torus distribution function for ion veloc-ity is obtained ,and the characteristic of the torus distribution function is analyzed .Meanwhile ,using the electromagnetic theory of the incoherent scattering proposed by Sheffield ,and taking into account the ion temperature anisotropy and its variation with the electric field ,the incoherent scattering power spectrum of ion in different direction is simulated .The research shows that the ionospheric electric field , the ion-neutral collision frequency and the ion anisotropic temperature distribution is all have an effect on incoherent scatter spectra ,the research content provides a theoretical basis for further understanding the high-latitude ionosphere and improving detection accuracy of the radar .关键词
