摘要: 提出通过C#和Matlab混合编程实现雷达回波数据采集和反演软件设计的方法。利用C#友好的界面实现用户接口,将Matlab编写的函数文件编译成共享库在C#中进行调用。以现有的大气激光雷达所采集数据为例,进行了回波数据采集、预处理及消光系数反演。运行结果表明,将C#界面开发的优势与Matlab强大的算法处理和仿真功能相结合,可增大运算速度并提高编程效率,软件可有效地应用于激光雷达系统的数据采集和监测,快速批量地实现回波数据预处理以及反演参数的实时动态显示。系统通过调整算法参数也可用于其它激光雷达信号的处理。

Abstract: C# and Matlab are presented for the design of lidar echo data acquisition and inversion software. With friendly user interface, C# is used to call the DLL format shared library compiled by function files wriiten in Matlab. The existing atmospheric Lidar echo data are applied as an example and the processing results show that this method can improve computing speed and programming efficiency. The software system can be effectively used in the data acquisition and system monitoring. Echo data are preprocessed efficiently with high precision. The retrieving extinction coefficient and echo energy accumulation are processed and displayed dynamically in real time. By adjusting algorithm parameters, it can also be used for other kind of lidar signal processing systems.

Key words: lidar, lidar data processing, extinction coefficient, mixed programming, software design
