Web1 okt. 2011 · While the Haselgrove ray tracing equations are well suited to situations where the ray launch direction is known, they are less effective for situations where only the end points of the ray are known. In such cases, many rays must be traced from the launch point in order to home in on the landing point. An alternative approach is to directly solve the … Web25 mrt. 2024 · The global 3D ionospheric data assimilation electron density produced by the algorithm of Yue et al. was used as the ionospheric background for ray-tracing.This algorithm assimilates multiple ionospheric real-world observations into the International Reference Ionosphere (IRI) background model through a Kalman filter scheme.
Webthe ionosphere greatly [14,15], when the ionosphere ED is given in two dimensions, ray-tracing program in the numerical way has to be used [16]. As to the numerical way of ray-tracing program, there are many researchers who have studied this subject. In view of the computational complexity of a ray-tracing program, analytic ray-tracing methods ... WebRocket ionosphere experiments give the relative delay of a pulsed signal as a function of rocket position. These data are used in an analysis to obtain the electron-density distribution with respect to height. This analysis, which takes into account the effects of the earth's magnetic field and the obliquity of the ray paths, is for the smooth, horizontally stratified …
