Ionosphere Fitting Method and Path Parameters Analysis
Anti-parabolic model was adopted to describe the joint layer’s electron density which distribute between the quasiparabolic multi-lays in ionosphere.The parameters of the antiparabolic layer,such as critical frequency,semi thickness and the layer bottom radial distance from earth’s center,were calculated on the basis of the continuous electron density distribution and its continuous derivative.The plasma frequency calculated in the quasi-parabolic model or anti-parabolic model was substituted into Appleton-Hartree formula and Snell theorem to calculate the ray trace with the help of ray geometry in the ionosphere.The three important path parameters which are the ground range,group path and phase path were calculated on this multi-layer ionosphere model with the joint layer.The relationship between the path parameters,which is influenced by the angle of incidence and the working frequency,was analyzed.
