| 摘 要： | 雷达回波外推是解决人工影响天气指挥炮点作业时间选取的有效途径。文章介绍了雷达回波外推的相关性跟踪方法（TREC）,由TREC矢量得到的回波移向移速,以6 min为间隔,线性外推4次回波,根据外推回波是否落在炮点的有效射程范围内,得到回波到达炮点射程范围的时间,为炮点作业时间的选取提供参考。个例分析表明,外推回波落在炮点有效射程范围的外推时间与回波实际落在炮点的有效射程范围内时间点基本吻合。

| Abstract: | Radar echo extrapolation is an effective way to select the operation time in rocket weather modification. The radar echo extrapolation method of TREC (Tracking Radar Echoes by Correlation) is described. Based on the echo shifting and moving speeds, echoes are extrapolated linearly within the range of the rocket shot, then calculating the time that the echoes arrives at the rocket shot to provide reference for the selection of operation time. The test indicates that the extrapolated time for echoes to reach the rocket shot is in consistent with the actual echoes. |
