Abstract

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 andobtain highly accurate optical properties of aerosols.
