中文摘要 | 拖曳式线列阵声纳所具有的低频、大孔径特性使其成为解决水下目标(舰艇)远程探测的重要手段之一。拖曳式线列阵声纳的发展趋势是采用细长阵(甚至全光线列阵(光纤水听器))技术和细拖缆拖曳,这就要求在进行声纳设计时,针对声阵段直径小的条件,既要考虑模块化、可扩展性要求,又要考虑数字化、网络化、高速率和低失真等要求。因此新型拖曳式线列阵声纳普遍采用把基阵信号数字化之后,通过光纤拖缆传送到声纳信号处理和/或信号记录系统的方式,所以高速数字传输系统就成为研究拖曳式线列阵声纳不可分割的有机组成部分。针对拖曳式线列阵声纳数据传输系统这一问题,在借鉴、发展、创新的基础上,本论文提出了一种设计方案并设计实现了一个高速数字传输系统。该方案利用COTS(Commercial Off The Shelf)产品,以模块化、可重构为设计思想,结合小型化、低功耗的工程要求,采用了当前主流技术成熟的DSP和CPLD产品,利用HOTLink的高速背板串行传输技术,充分利用三者的优势,以稳定的拓扑结构实现了这一复杂的传输系统。系统结构简单,稳定可靠,结合干端控制系统在功能上具有很大的扩展性。 |
英文摘要 | Towed array sonar (TAS), with the property of low frequency and big aperture, has been employed as one of important ways to settle remote detection of under water object. Fine-line array sonar and fiber one are key trend of TAS. As the result of that, new requirements for sonar design are proposed, such as digitalization, network interface, high speed, low distortion as well as modularization and expansibility, the further discussion about the question is that the signal is transmitted to the signal processing system or signal recording one through fiber after sonar signal is digitalized in the new TAS, therefore, high speed transmission system has become integrated part of modern TAS. This design makes use of mature technology in commercial area, adopting widespread COTS availability to build up the whole system in modular and re-configurable form. The design uses the mainstream and high performance DSP and CPLD as well as HOTLink high-speed serial transmittal technique to frame the steady and high flexible system, and make it possible to expand function easily without making any hardware change. The design idea and implementation of system as well as debug process is discussed in detail. The result of experiment shows that the system has satisfied the designed specification. |
