大气遥感双视场米散射激光雷达信号拼接

摘要

We presents an effective signal splicing method for dual-receiver mie scattering lidar. The main idea of this method is to find the best spliced region where both near-range signal and far-range signal have high signal-to-noise ratios and to obtain the functional relationship between these two kinds of signals so as to achieve effective splicing and retrieval of near-range signal and far-range signal. The signal splicing result has both advantages of low detection dead zone in near-range signal and high detection height in far-range signal. The signal retrieval result demonstrates that this method can splice signals accurately and obtain highly accurate optical properties of aerosols.%介绍了一种双视场米散射激光雷达信号拼接方法.主要思想是寻找近场和远场信号都具有高信噪比的最佳拼接区域,求解该区域两种信号之间的函数关系,自动实现激光雷达近场信号与远场信号的有效拼接和反演.拼接结果兼具近场信号探测肓区低和远场信号探测高度高的优点.反演结果表明,该方法能够准确有效地实现双视场信号拼接,并能反演得到高精度的气溶胶光学特性.
