查询词典 November meteor

The observational result shows that this Quadrantid meteor shower occurs between 0000 to 0800 local time in January 4, 2004, with meteor echoes peaking at 0400 local time. Moreover the meteor shower radiant derived from the meteor echoes plane, which is formed by the whole meteor echoes observed by the meteor radar during this shower, accords well with the theoretic radiant of this meteor shower.

从观测结果可以发现此次象限仪座流星雨发生在2004年1月4日的0000-0800LT，其中流星峰值出现在0400LT，而且通过流星雷达观测到的流星雨期间的流星回波平面推测得到的流星雨辐射点也与该流星雨的理论辐射点位置对应非常好。

The Quadrantid meteor shower and the meteor speed during the period of this meteor shower are successfully observed using the Wuhan meteor radar for the first time, and then the correlative questions of observing meteor shower using the all-sky meteor radar are also discussed.

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea, a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious. Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter.

该文根据地海杂波与流星干扰在多普勒谱上的差别，提出了用FIR型高通滤波器滤除杂波使流星干扰凸显出来；再根据流星干扰的分布特点分段计算背景噪声均值，求取流星干扰检测门限；最后用杂波信号来插值流星干扰位置上的数据，消除因去除干扰造成的杂波相位不连续。

Perseid meteor shower is an annual fixed July 17 to August 24 during that time, it is not only quantity, but almost never in the absence of the Star in the summer before, is the most suitable non-professional meteor observers of the meteor shower, status column throughout the year the first three periodic meteor showers.
