摘要
本文针对航空声呐要求远距离实时传输多通道水下声数据的实际需要，研制了一种利用Manchester码实现的高速数据传输系统。其误码率小于10(-7)，数据传输率为3Mb／S，最高可达13Mb／S，传输距离超过500米，并可用于1000米以上的远距离传输。该系统已成功地用于某型航空声呐的数据传输中，并可推广应用于其它需要远距离高速传输多种数据的场合。
According to the tactical requirements of aviation dipping sonar equipments, a system for 1ong-range high rate transmission of multichannel underwater acoustic data employed Manchester code is lntroduced ln this paper. In order to transmit various signals bi-directionally through a single-lead coaxial cable in real-time,a hybrid technlque scheme of frequency-sharing plus time-sharing is proposed. The bit error rate of the transmission system ls lower than 10-7,bit transmission rate is between 3Mb/s～13Mb/s,transmission range is above 5OOm,and the maximum range can reach 1000m. The system has been used for data transmission system of one type aviation sonar equipment successfully,and can be used in underwater robots, underwater imaging,benthic observation and so on to transmit varlous types of signals with high data transmission rate. It can also applied in scenarios,in which transmission cable size and weight are strictly restricted and high speed data transmisslon is requlred.
