基于剪贴板及COM技术设计实现雷达宽带直采回波提取软件

Software Design and Implementation of Echo Waves Extraction of Direct Acquisition Wideband Radar Based on Clipboard and COM Technologies

为有效地从雷达宽带直采数据中获取空间目标的信息,为后续的目标识别提供支持,设计雷达宽带直采回波提取软件很有必要。软件实现采用了三种关键技术:一是采用COM技术提高已有组件的重用性及开发效率;二是利用Windows剪贴板作为COM组件和软件主程序间通信媒介实现不同进程间信息交换;三是使用多线程技术提高软件运行效率和交互性。该软件已成功应用于工程实践,提高了雷达宽带直采数据的处理效率,证明了软件设计的正确性。

With the demand for effectively extracting spatial objects’ information from direct acquisition wideband radar data and giving support for subsequent target classification comes the need to design an echo wave extraction software on wideband direct acquisition radar. Three key tech-nologies are utilized in the software implementation. First, the utilization of COM technology facil-itates the component reusage, thus enhances software design efficiency. Second, the Windows clipboard acts as a mechanism to exchange data between the COM and the software main procedure. Finally, the multithreading technology makes it possible to improve efficiency and interactivity of software. This software is successfully put into practice, which increases data processing efficiency of direct acquisition wideband radar data. It is clear that the software design is correct.
