摘要
在分析传统水下蔽障原理基础上,针对基于单波束的换能器阵列水下蔽障系统展开设计。系统筛选DSP和模拟数据选通芯片实现换能器阵元逐次扫描,采集回声信号调理后合成水下图像。研究了发射、接收的硬件电路设计,基于DSP的系统软件设计思路与流程,经过实验验证了设计的可行性。
Akstraet：A designing method of underwater obstacle avoding system method based on single-beam is proposed, according to the a- nalysis of obstacle avoiding principle. The system scans uses DSP and analog data selector so that transducer array can scan continuously and underwater image can be generated by processed echo signal. The design of transmitting and recieving hardware is introduced em- phatically in this paper. And it describes the design of software based on DSP. It attests designing method feasible after experiment.
