摘要
在被动传感器系统中,快速、准确的定位技术对于数据的关联、目标的跟踪至关重要。为解决网状被动传感器系统中目标定位问题,该文提出了垂线定位法。仿真实验结果表明,垂线定位法是一种有效的目标定位方法,其定位误差的方差能达到Cramer-Rao下界。
Fast and precise location method plays an important role in the data association and the target tracking for the passive sensor system. In order to solve the typical problem of the target location encountered in the netted passive sensor system, the vertical location method is proposed. Simulation results show that the vertical location method is an effective target location method, and its positioning error variance can achieve the Camer-Rao lower bound.
