综合了已有的机载激光雷达测深系统的波形处理方法。基于国产多通道海洋激光雷达波形数据的多通道优势,运用去卷积、数值拟合和信号滤波等波形处理方法,针对不同类型的波形,提出了一套适用于国产硬件的波形处理方法。该方法可保证回波位置提取的稳健性。
Abstract
The existing waveform processing methods in the airborne Lidar bathymetry system are reviewed. Based on the multi-channel advantages of the domestic airborne Lidar bathymetry waveform data and by using the multiple waveform processing methods, such as deconvolution, numerical fitting and signal filtering, a set of waveform processing methods suitable for domestic hardwares is proposed as for different types of waveforms. This set of methods can ensure the robustness of waveform peak position extraction.
