| 摘 要： | 在雷达硬件标定正确的情况下,多普勒天气雷达基数据的质量主要受到3个因素的影响1]。这3个因素分别是地物杂波、距离折叠和速度模糊。在本文中我们主要分析了其中的速度模糊现象出现的原因,着重介绍交错脉冲法（也叫双脉冲重复频率法,即DPRF）解速度模糊,同时结合3830天气雷达解速度模糊的特点,证明了交错脉冲法可以有效地扩大无模糊测速范围。

| Abstract: | On the right condition of radar hardware calibration, the data quality control in pulse Doppler weather radar is affected by three factors： ground clutter, range overlaid echoes and velocity ambiguity. In this paper, the cause of velocity ambiguity is investigated, and double-pulse repetition frequency （DPRF） method is emphatically introduced. At the same time, combined with the characterictics of 3830 weather radar velocity ambiguity resolution, it proved that DPRF effectively expand the scope of non-ambiguity speed measurement. |
