Abstract

The initial results of a new cycle (since 2016) of meteor observations in Kazan (56◦N 49◦E) which is associated with equipping of Kazan Federal University (KFU) with the new meteor radar SKiYMET are given. Simultaneously with the processing of experimental data using the built-in (native) software SKiYMET, the processing was performed using the new software developed in KFU. A comparative analysis showed a significant increase in the number of registrations due to the processing of meteors that are weaker with signal-tonoise ratio. The seasonal and daily dependencies of the meteor number for the period 2016-2019 are given. The obtained distributions of entry meteor speeds and their dependencies by seasons and heights of meteor trails are separately considered. The method of data processing for obtaining coordinates of meteor shower radiants in the equatorial coordinate system is described. The results of observations of the Geminids, Eta Aquariids, Arietids, April Lyrids, Northern and Southern Daytime Omega-Cetids, Daytime Lambda Taurids and Daytime Arietids meteor showers are presented.

KFU流星雷达对流星雨的观测

喀山新一轮（自2016年以来）流星观测的初步结果（56◦N 49◦E）介绍了为喀山联邦大学配备新型流星雷达SKiYMET的情况。在使用内置（本地）软件SKiYMET处理实验数据的同时，使用KFU开发的新软件进行处理。一项比较分析显示，由于对信号噪声比较弱的流星的处理，登记数量显著增加。给出了2016-2019年期间流星数量的季节性和日相关性。分别考虑了所获得的入射流星速度的分布及其随季节和流星轨迹高度的相关性。介绍了在赤道坐标系中获取流星雨弧度坐标的数据处理方法。给出了双子座、埃塔水族馆、Arietids、April Lyrids、北方和南方日间Omega Cetids、白天Lambda Taurids和白天Arietids流星雨的观测结果。
