INTELLIGENT DIRECTIONAL FULL-DUPLEX UNDERWATER ACOUSTIC COMMUNICATION APPARATUS AND COMMUNICATION METHOD THEREFOR

摘要

Provided are an intelligent directional full-duplex underwater acoustic communication apparatus and a communication method therefor. The intelligent directional full-duplex underwater acoustic communication apparatus comprises a transmitting transducer array, an electronic cabin and a vector hydrophone, wherein the electronic cabin comprises a waterproof connector, a modulation and demodulation board, a power amplifier, a vector signal amplifier and a compass module, the modulation and demodulation board being respectively connected to the waterproof connector, the power amplifier, the vector signal amplifier and a compass, the power amplifier being connected to the transmitting transducer array, and the vector signal amplifier being connected to the vector hydrophone; and the electronic cabin is provided with a power supply module for supplying power to the other modules in the electronic cabin. In the present invention, a transducer array is used to realize the directional transmission of a signal, thereby improving the transmission efficiency; a vector hydrophone is used to realize the directional reception of a signal, thereby improving a signal reception gain; directional transmission and reception algorithms are realized in a DSP; and the space directivity of the vector hydrophone can inhibit strong signal interference generated by a local transmitting transducer well, so as to realize full-duplex communication.
