摘要	介绍了自行研制的用来探测对流层大气气溶胶消光特性的双视场米散射激光雷达．该激光雷达采用两个具有独立接收视场的探测通道分别接收高低层532nm的大气回波信号，可以兼顾低层大视场角低探测盲区和高层小视场角高探测高度的要求．叙述了该雷达系统的总体结构和技术参量以及数据处理方法，给出了合肥地区（东经117．16°，北纬31．90°）大气气溶胶消光系数廓线和对流层光学厚度的探测结果．测量结果表明，该雷达具备昼夜连续观测对流层大气气溶胶的能力，可以很好地反映气溶胶粒子的时间和空间分布特征．
其他摘要	A dual-field of view lidar system with two receivers was developed to measure tropospheric aerosol extinction coefficient profiles at 532 nm wavelength and its spatial and temporal variations. Two channels were designed to receive the far and near range baekscattering signal with different FOV. Farrange atmospheric baekscattering light is received by a bigger aperture telescope with a narrow FOV and near-range measurements employed a smaller aperture telescope with a wide FOV, through which can satisfy the needs of low dead zone in near-range and high detected height in far-range. Overall structure and specifications of the lidar were described. Lidar data processing method was also presented. The lidar system was operated at Hefei（117. 16° E, al. 90° N）. The extinction coefficient and optical thickness of tropospheric aerosol derived from lidar signal were presented and discussed. The observational results show that this lidar works well both during the day and at night and can to measure the tropospheric aerosols and to manifest the temporal and spatial distributions of the aerosols with high precision.
