A dispersão de uma onda plana incidente obliquamente em uma trilha de meteoro é estudada usando o tratamento de onda completa, tratando a trilha como uma coluna estratificada que possui distribuição eletrônica radial gaussiana. Devido ao acoplamento dos campos, as equações acopladas devem ser resolvidas simultaneamente. Eles são tratados em forma de matriz, para que os componentes desacoplados e acoplados possam ser distinguidos. Com base na geometria de espalhamento oblíquo, são investigados os efeitos da variação do alcance de comunicação e da orientação da trilha. No caso da variação do alcance de comunicação, os resultados estão de acordo com os modelos aproximados, mas contrastam no caso da variação da orientação da trilha. As formas de onda calculadas são comparadas com as formas de eco experimentais. Verifica-se que eles estão de acordo entre si. Além disso, uma comparação de duração indica que as densidades das linhas de elétrons da maioria dos sinais recebidos estão na região de transição.

Abstract: 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.
