摘 要：[1]Interferometry measurements of range spread meteor trail echoes(RSTEs;also known as nonspecular echoes) have provided new insights into both the irregularity structures in meteor trails and lower-thermospheric winds(LTWs).In this study,we used trail echoes observed with the newly installed Sanya(18.4°N,109.6°E) 47.5 MHz VHF coherent radar
