在一实施例中,确定第一发送时间及第二接收时间后,可以得到声波在第一移动终端与声呐设备之间的传播时间,由于声速已知,进一步可以得到第一移动终端与声呐设备之间的距离。例如,设声速为v,第一发送时间为T 1,第二接收时间为T 2,则声波在第一移动终端与声呐设备之间的传播时间可以为(T 2-T 1)/2,第一移动终端与声呐设备之间的距离L=V×(T 2-T 1)/2。
进一步地,声呐设备的定位可以通过定位装置获得,确定第一移动终端与声呐设备之间的距离后,结合声呐设备的定位可以计算第一移动终端的第二位置。
在一些实施例中,确定第一移动终端的第二位置的方式可以是:
获取声呐设备的延时时间,延时时间由声呐设备接收到第一声波信号的第一接收时间及声呐设备发送第二声波信号的第二发送时间确定;根据第一发送时间、第二接收时间及延时时间,确定第一移动终端的第二位置。
在一实施例中,声呐设备从接收到第一声波信号到发送第二声波信号之间可能存在一定的延时,在此情况下,设声速为v,第一发送时间为T 1,第二接收时间为T 2,延时时间为T 3,则声波在第一移动终端与声呐设备之间的传播时间可以为(T 2-T 1-T 3)/2,第一移动终端与声呐设备之间的距离L=V×(T 2-T 1-T 3)/2。然后,根据声呐设备的定位以及第一移动终端与声呐设备之间的距离可以确定第一移动终端的第二位置。
