| 摘 要： | 在简述短基线相差测距和测角的基础上,利用正弦定理可给出两种大跨距双站交会角的单站测算方法,一种直接利用单站测距,另一种利用虚拟站点处对目标的虚拟测距。误差分析表明,采用虚拟测距的方法能有效提高单站虚拟测角的精度。

| Abstract: | On the basis of simply describing the ranging and DF based on short-baseline phase-difference measurement, two computation methods observing the cut angle between two stations by single-station is presented by sine theorem. And the span between two stations is big. One is directly using the radial distance between single-station and target. The other is using radial distance between target and dummy station. The error analysis shows that the method using dummy ranging can effectively enhance the angulation precision of single-station observation. |
