摘　　要：对非相干米散射多普勒测风激光雷达单Fabry‐Perot干涉仪双边缘鉴频系统进行理论研究。证明通过适当地降低此系统斜入射通道信号光的发散角可以有效地弥补其边缘曲线不对称产生的测量精度降低的缺陷，使其能够接近双Fabry‐Pero t干涉仪双边缘鉴频系统的测量精度。还证明此系统可以根据实际风速的需要调整其测量动态范围以获得更高测量精度，具有更高的灵活性。
The single Fabry‐Perot interferometer （FPI） double‐edge structure in incoherent Mie Doppler wind Lidar is investigated theoretically .It has proved that ,by reducing the divergence of nonzero angle beam of this structure appropriately ,the deficiency caused by the asymmetric edge curves can be made up effectively and can have approximate equal measurement accuracy with the double FPIs double‐edge structure .It also has proved that the Lidar system with this structure can tune the measuring dynamic range for wind velocity requirement to reach as high measurement accuracy as possible and has a strong adaptability .
