摘要
本文研究利用外辐射源的单站无源定位和跟踪技术的可观测性问题。引入相容目标轨迹的概念,分析了三维N阶运动目标在不同观测信息条件下的相容轨迹的几何分布,并证明多普勒和到达时差观测是等价观测量。
This paper studies the state-observability problem for single observer passive locating and tracking using radiation reflected by target from external transmitter. By introducing the conception of compatible target trajectories, this paper analyzes compatible trajectories' geometric distribution of three-dimensional N-order dynamics target under the different observation information condition and also shows that Doppler measurements are equivalent to arrival time difference measurements .
