This paper discusses the passive location techniques using TDOA & FDOA,and proposes the method to locate target position using joint TDOA and FDOA.Simulation results indicate this method is feasible.

讨论了多站时差(TDOA)和多普勒频差(FDOA)无源定位技术,并将时差定位与多普勒频差定位结合起来,提出了对运动目标的时差-多普勒频差联合定位思想。仿真结果表明,这一方法是可行的。

In traditional passive location techniques to emitter as radar,the cross of direction lines by the use of DOA(direction of arrival) information is a main method.But the method maybe leads to worse accuracy or slower convergence. An EKF(Extended Kalman Filter) algorithm is discussed which adds PRC(Phase Rate of Change) information.Influence to location accuracy of DOA,PRC and DOA-PRC is analyzed respectively.And comparison between two algorithms is also given by the simulation results.

传统的无源定位方法主要是利用到达方位角(DOA)信息对雷达等辐射源进行测向交叉定位,但由于该方法对测角精度的敏感性,仅利用DOA信息会导致定位精度低,算法收敛时间长等不良后果。本文探讨了一种融入相位变化率(PRC)信息的推广卡尔曼滤波(EKF)算法,通过仿真,分析了DOA与PRC单独测量与联合测量对定位精度的影响,同时,将融入PRC信息的EKF定位算法与只测角定位算法进行了比较。
