摘要

Non-specular meteor trail echoes are radar reflections from plasma instabilities, which are caused by field-aligned irregularities (FAI). Here, we reported on characteristics of non-specular trail echoes frequently detected with 53 MHz Gadanki ( \(13.5^\circ \) 13 . 5 ∘ N, \(79.2^\circ \) 79 . 2 ∘ E) MST radar. These echoes are characteristically different in size and nature, having non-specular reflections over several range-bins with several seconds of duration. We presented few representative examples of such echoes detected with Gadanki MST radar. These examples were analysed and discussed on case by case to understand their evolutionary mechanism. Based on the current understanding of meteor trail theories, we also discussed the most possible factors responsible for the evolution of such echoes.
