Experimental Study of Trans-Medium Communication of Millimeter-Wave Radar in Wave Tank
Wireless cross-medium communication for underwater equipment may be possible by using millimeter-wave radar to detect the micro-wave vibration on the water surface excited by sound waves of underwater equipment.Studying the effect of water surface waves is of great value for achieving trans-medium communication based on micro-wave vibration detection by millimeter-wave radar.Therefore,experiments were carried out on the trans-medium communication of binary phase-shift keying(BPSK)and binary frequency-shift keying(BFSK)modulation signals in a wave tank.The influence of different water surface wave vibrations on trans-medium communication was tested and analyzed,and the communication performance based on spatial diversity technology was evaluated.The experimental results show that moderate water surface wave vibrations have the least impact on the trans-medium communication performance of millimeter-wave radar,and the spatial diversity technology based on multi-channel data merging can improve trans-medium communication performance on wavy water surfaces.The research results can provide a reference for practical applications of trans-medium communication technology based on micro-wave vibration detection by millimeter-wave radar on wavy water surfaces.
