VPP方法对小尺度风场结构中心区域的反演展现了良好的性能，但在边缘区域，由于风速变化剧烈，破坏了径向风场的连续性，导致反演算法在该区域失效。研究了受干扰的反演区域的识别和定位方法，推导出同一个径向上水平切向风速一致，依此对水平切向风速修正，提出一种改进的VPP反演算法，采用该方法反演模拟的小尺度辐散风场，仿真结果验证了方法的有效性。

VPP retrieval algorithm shows good performance among the central region of micro scale wind filed. But on the edge, the wind field changes dramatically, destroys the continuity, and makes the retrieval method invalid. The method of identifying and locating the interference inversion region was studied. It was derived that horizontal tangential wind speed was the same at the same radial, thus the initial inversion results were corrected. An improved algorithm was put forward. The experiment was conducted using simulated doppler lidar data to prove the method, and it is proved to be effective.
