摘要
相关测速声纳是利用"波形不变性"原理的测速声纳,其通过对回波的理论时空相关函数和数据时空相关函数进行最小二乘拟合或其他优化算法来解算载体速度。搭建一套功能完善、运行稳定、性能可靠的软硬件系统,是相关测速声纳研制工作的最重要环节。软硬件系统的可靠性和稳定性为验证相关测速理论提供了基本保障,是相关测速技术走向应用的关键。本文研究相关测速声纳软硬件系统的组成结构及设计方法,对于硬件系统和组成软件系统的三部分软件分别进行介绍。
Correlation Sonar, which works on the principle of ＇ waveform invariance＇, obtains the velocity of vessel by least - square fitting the theoretical correlation function and correlation function of data or other optimization method. Building a well - functioning, stably - running, well - performing system both in hardware and software, is the key process of the design of correlation sonar system. The security and stability of the hardware and software system can guarantee the verification of the correlation sonar theory and also leads the correlation sonar technology to application. This paper introduces the design method and structure frame of the correlation sonar system, including the hardware system and three parts of the Software system.
