| 中文摘要 | 目前，针对港口、海港、海洋工作平台、石油天然气设施、船只以及海岸设施的恐怖威胁日益严峻。这已经成为一种现实的，引起沿海国家高度关注的问题。恐怖袭击一旦发生，不但造成灾难性的人员伤亡和重大财产损失，甚至严重影响国民经济的稳定运行。 恐怖分子利用一个低成本的不需要任何科技含量的蛙人就可以造成巨大的人员伤亡，经济损失甚至军事打击。这种非对称的恐怖袭击促使船舶和港口研制并且使用蛙人探测声呐。 便携式蛙人探测声呐是专门为海军基地、商业港口、深海油田、船只、海岸设施等设计，用来对抗进行恐怖袭击和破坏活动的蛙人。该系统可以跟踪和处理水下可疑目标，及时为操作人员提供警报。 第一，调研了蛙人探测声呐的发展历史； 第二，阐述了系统的测量原理，研究了旋转基阵接收信号的物理模型，重点研究了旋转基阵的波束形成算法和角度补偿，进行了Matlab仿真； 第三，设计了以旋转基阵为核心的便携式蛙人探测声呐的整体架构，着重讨论了数据处理模块原理设计和工程实现； 第四，编写了DSP软件，重点说明网络驱动程序和TCP/IP协议栈的实现，确保了有效可靠的数据传输； 第五，设计了系统显控软件和用户界面。 |
| 英文摘要 | The threat of terrorist on ports, harbours, offshore platforms, oil & gas installations, shipping and coastal facilities is today sadly, a real and growing concern to all maritime countries and one which could severely affect their economic stability not to mention the catastrophic loss of life and damage to infrastructure a serious terrorist attack could led to. Today, a single terrorist diver equipped with a low-cost and low-tech payload could cause huge loss of life and significant military or economic disruption. The threat of asymmetric attacks against ships and harbours led to the development and launch of a new diver detection sonar. The Portable Diver Detection Sonar is designed specifically to counter the threat of sabotage and terrorism to naval bases, commercial ports, oil platform, shipping, coastal facilities etc. The system is designed to track and process underwater threat in order to provide alarms for operators to act on. First, investigated the development history of diver detection sonar. Second, explained the ranging principle of sonar system, studied the receive signal model of rotary array, focused on the beamform algorithm of rotary array and angle compensation solution, simulated the beamform algorithm in Matlab. Third, designed the framework of the portable diver detection sonar based on rotary array, focused on the schematic design and hardware implementation of digital signal processing module. Fourth, developed the software of DSP, focused on the ethernet driver, implemented the TCP/IP stack, made it carry out effective and reliable data transmission. Fifth, developed the display-control software and its GUI display. |
