摘要
Abstract
The information synchronization problem is one of the difficulties in the application of multi-base active sonar systems.In existing research and application,it is usually assumed that the receiving station knows the pulse transmission time of the transmitting station,the spatial location information of the sound source,and the transmission waveform parameters,thus can calculate the echo sound path,locate the target,and obtain the time processing gain of the echo signal.However,these conditions may not be met in practice.The obstacles and possible solutions for information synchronization in different application scenarios were first discussed.A multi-base active location method based on cross-domain information synchronization was then proposed for the situation where there is an external communication link between the receiving and transmitting stations,but the link is unreliable,or the delay is uncertain.This method used the basic physical law that the direct wave arrives at the receiving station before the target echo.The receiving station first obtained the position and waveform parameter information of the transmitting station through the external link and then estimated the transmission time according to the direct wave arrival time and the distance between stations.It had high engineering feasibility.Finally,the factors affecting the accuracy of time and position synchronization and the target positioning error caused by the time and space information error were discussed and simulated.关键词
