- Of course, the streaks are meteor trails from the annual Geminids meteor shower. 当然，这些轨迹是每年发生的双子座流星雨流星划过天空的轨迹。
- The large gap in the single meteor trail corresponds to the time gap between the consecutive frames. 因为每帧画面之间会有时间空档，单颗流星的光迹中便留下了大大的间隔。
- Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. 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；
- The meteor trail echo is one of the main interferences and has to ho suppressed since it severely degrade the detection capability of high-frequency radar. 摘要流星余迹回波是高频雷达的主要干扰源之一，严重影响了雷达对目标的探测性能，必须加以抑制。
- Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter. 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。
