Scattering of a plane wave obliquely incident on a meteor trail is studied using the full wave treatment by treating the trail as a stratified column which has Gaussian radial electron distribution. Due to the coupling of the fields, the coupled equations have to be solved simultaneously. They are treated in matrix form, so the uncoupled and the coupled components can be distinguished. Based on the oblique scattering geometry, the effects of the variation of the communication range and the trail orientation are investigated. In the case of the variation of the communication range, results are in accordance with the approximate models but they are in contrast in the case of the variation of the trail orientation. Calculated waveforms are compared with the experimental echo shapes. It is found that they are in good agreement with each other. Furthermore, a duration comparison indicates that the electron line densities of most of the received signals are in the transition region.
