this method includes two kinds of observation data for the correlation rule, hence resulting in enhanced spatial resolving capability . weighted track fusion with cep as weight is proposed . this method has less calculation and notable result 同时根据无源定位系统观测误差的分布特性,提出了以为权因子的加权航迹融合算法,该融合算法计算量小,效果显著。
because the sonar system have high frequency, high resolving capability and 128 receiving channels, the unit can not only sampling, store and translate the receiving sound-signals, but also have the property of lower power 由于声纳系统工作在高频率,并且具有高分辨率和128个接收通道,所以水下单元的设计不仅能够对接收声信号进行高速采集、存储和传输,而且还具有低功耗,。
