摘要
在采用和现有固定单站纯方位目标运动分析相同的测量手段,且对目标相邻移动距离不做任何限定的一般情况下,充分利用简单的平面几何关系,并通过引入自时差测量方程,完整地给出了求解目标航向角、目标移动速度和移动时差、目标与单测向站之间径向距离等参量的解析计算公式,所提出的新方法突破了现有的仅利用距离与速度之间的关系的固定单站纯方位无源探测仅能获得目标航向,以及速度与初始距离比值的局限性.
Using the measuring instrumentality that is exactly the same as the available bearings-only target motion analysis of fixed single station, in the case of the adjacent traveling distance of target being inequality, the solving formula for bearings-only pas- sive location of fixed single station, which can solve the target path angle and moving speed as well as radial distance between target and fixed single station, is perfectly pres- ented based on the simple plane geometry relationship and by introducing the self time difference measuring equation. New method presented in this paper pierces through the limitation in available method that can only obtain the target heading and the ratio be- tween target speed and initial radial distant only using the relationship between distance and speed.
