| 英文摘要 | Observations on range spread trail echoes (RSTEs) have been generally limited to high power large aperture radars. In this study, we use trail echoes observed with the Sanya (18.4 degrees N, 109.6 degrees E) VHF radar to investigate the occurrence characteristics of RSTEs. The observational results show that the generation and evolution of RSTEs detected by the low power coherent radar are similar to the RSTEs measurements made with high power radars. The time-height distributions of RSTEs and specular meteor trail echoes (SEs), respectively observed by the coherent scattering and the all-sky meteor detection modes of the Sanya VHF radar during August 2011, are also investigated. For short-lived RSTEs (<15 s), the mean time-height distributions are consistent with those of SEs. However, SEs and long-duration RSTEs show significant differences in the peak occurrence time and height dependence. It is found that the long-duration RSTEs (>= 15 s) occur earlier in the dawn side and show a clearer dependence on altitude. Furthermore, the number of SEs is greater than that of RSTEs, which could be associated with the radar beam width and viewing geometry. |
