等速运动观测站纯方位系统的可观测性

Observability Analysis for Single Bearings-only Observer Traveling with Constant Velocity

对等速直线运动单观测站纯方位目标运动分析问题进行了讨论。尽管系统是不完全可观测的,却证明了目标部分运动参数是可估计的,即目标与观察者的相对航向Kr、相对速度与初距离之比Vr/Do是可以解算的;并对可估计参数的有解条件进行了分析。

The bearings-only target motion analysis problem about a single observer traveling with constant velocity is discussed in this paper.It is shown that some of the target motion parameters(the relative course Kr and the ration of relative speed to inital distance Vr/Do)are observable,even the system is unobservable.The observability requirements for those parameters is established.
