| 摘 要： | 在深入分析速度模糊的特点后,根据在距离圈上不模糊点到模糊点的不连续性,以及对模糊跳变处风速差和最大不模糊速度间关系的判定,从零方位开始在距离圈上逐点进行速度模糊的判定,并引入模糊标记的形式以确定退模糊处理的区间.然后通过实例分析,证明了方法的可用性和正确性.最后利用经过该方法处理的低仰角基本速度资料成功反演了雷达风场.

| Abstract: | According to the discontinuity in the process of the ambiguous data transferring to the unambiguous data and the relationship between the velocities on the jumping azimuth with the maximum unambiguous velocity the judgment of the ambiguous velocity is performed having analyzed the feature of the ambiguous velocity.A soft sign is introduced to demarcate the ambiguous segments.The correctness and usability of this method are proved by the sample analysis.The radar wind field is retrieved successfully based on... |
