摘要
空中运动目标无源定位和跟踪技术近年来一直是人们研究的热点,这种技术在航空、制导等领域都有广泛的应用,有着广阔的应用前景。探讨了一种基于辐射源的信号到达时间差(TDOA)和信号到达方向(DOA)信息,利用固定单站对机动目标进行无源定位与跟踪的新方法。在建立目标机动模型与测量方程的基础上,运用修正增益扩展卡尔曼滤波(MGEKF)算法,实现对机动目标进行定位与跟踪。讨论了它的若干技术问题、定位原理与算法。通过计算机仿真,验证了该方法的正确性与有效性。
Passive location and tracking of moving target in space is a key problem in recent years. The technology has been widely applied in the fields of aviation and guidance. It has expansive prospects for application. The Modified Gain EKF （MGEKF）algorithm for passive location of maneuvering target by single station is discussed. Based on the Time Difference of Arrival（TDOA） and the Direction of Arrival（DOA） of the emitter, passive location by single station is practicable, and also the location of maneuvering target is practicable with the MGEKF algorithm, Some issues concerned, such as technical problems, principle and algorithem are discussed in this paper. With the help of computer simulation, the method is proven to be correct and effective.
