摘要

本文开发了一种集成水下通信和探测的嵌入式系统。具体来说,它由一个集成波形调制器、一个回波信号检测器和一个通信波形解调器组成。对于波形调制器,采用时分调制技术设计混合频率多载波(MC)波形,使通信信号和检测信号集成在同一信道上。在此基础上,设计了回波信号检测器,通过频域匹配滤波器提取时延和多普勒频移来估计目标参数。同时,开发了通信波形解调器,通过解调频域MC映射来接收数据。最后给出了实验结果,验证了嵌入式系统的有效性。

Design of an Embedded System for Integrated Underwater Communication and Detection
This letter develops an embedded system for integrated underwater communication and detection. Specifically, it consists of an integrated waveform modulator, an echo signal detector and a communication waveform demodulator. For the waveform modulator, the time division modulation technology is adopted to design hybrid frequency multicarrier (MC) waveforms, such that the communication and detection signals can be integrated on the same channel. Based on this, the echo signal detector is designed to estimate the target parameters by extracting the delay and doppler frequency shift with a frequency domain matching filter. Meanwhile, the communication waveform demodulator is developed to receive data by demodulating frequency domain MC mapping. Finally, experimental results are given to verify the effectiveness of our embedded system.
