摘要
水面多节点声呐动态网络由多艘观测接收船和多艘信号发射船构成,每艘信号发射船与每艘观测接收船上的声呐构成一组双基地声呐。为得到较高信噪比和定位精度,可利用双基地声呐的检测覆盖范围和定位误差分布特点,求得信号发射船、观测接收船、目标的最优布局图。通过分析可知,在跟踪运动目标时,如果观测接收船运动速度大于目标运动速度,那么观测接收船以最优布局图为依据进行机动,在跟踪目标一段时间后可获得最优跟踪精度;如果观测接收船运动速度小于目标运动速度,那么观测接收船更适合以静态方式跟踪目标。本文的分析结论对于战场环境下舰船指挥和控制具有较强指导意义。
Muhistatic sonar dynamic network usually consists of many observation ships and many signal transmitted ships. Each observation ship and each signal transmitted ship compose a group of bistatic sonar. For each bistatic sonar, the detecting area and the locating error distribution have their own characteristics. To obtain higher signal-to-noise ratio and higher locating precision, these distribution characteristics can be used to infer the ships＇ optimal positions. It is proved that when the observation ships are faster than the target, the optimal tracking performance can be obtained after some time by maneuvering the observation ships to the optimal positions. On the other hand, when the observation ships are slower than the target, the static tracking modes are more suitable for the observation ships. This conclusion is meaningful for controlling and maneuvering ships in battle fields.
