导航雷达回波信号的实时采集与回放

Real-time Acquisition and Review of Marine Radar Echo Signal

本文设计并实现了一种导航雷达回波信号的采集方法。在分析采样信号特性及雷达性能参数的基础上,采用PXI系统构建实时采集导航雷达回波信号的硬件平台。在此基础上,利用VC++6.0开发基于Windows操作系统的采集软件,并指出实现过程中的关键问题和解决方案。通过渤海湾某海域的岸基采样实验,证明采样方案的有效性和基于PXI技术采样平台的可靠性。

This paper presents a method of acquiring echo data of marine radar, shows the design and realization of the acquisition with the key points detailed. Base on the analysis of the acquiring single and radar performance parameters, the DAQ platform is designed on PXI hardware, and its software is developed by Mierosoft Visual C＋＋ 6.0 IDE on Windows operation system. The subsequent shore-based experimentation in Bohai bay shows the feasibility and the validity of the platform.
