Систематические ошибки измерения концентрации электронов в ионосфере методом фарадеевского вращения и способ их компенсации

Abstract

The technique of measurement of the ionosphere electron density by incoherent scatter radars with the use of Faraday Effect is considered. Bias errors of electron density measurement that arise because of the inexact polarization adjustment of receiving antenna are studied. A formula for the estimation of the referred errors is obtained. The method for compensating these errors is offered. The method allows obtaining good estimation of the electron density even if polarization adjustment of the antenna is not accurate. The method allows also to control accuracy of the polarization adjustment of receiving antenna. The results of numerical simulation and experimental results obtained by incoherent scatter radar of Institute of Ionosphere (Kharkiv) are presented.
