| 摘 要： | 利用机载观测站与辐射源之间的相对运动信息,在方位角测量的基础上增加相位差变化率的测量,可以对固定目标实现即时定位,为了提高精度,需要利用滤波算法进行跟踪滤波.在机载单站无源定位原理研究的基础上,通过计算机仿真分析了该定位方法下KF、EKF和MVEKF多种滤波算法的性能,对工程应用具有一定的参考意义.

| Abstract: | Using measurements of phase difference changing rate,as well as azimuth angle and relative motion between airborne observer and emitter,real-time location to fixed targets can be finished.To improve locating precision,filtering algorithm should be adopted.The principles of airborne single observer passive location are firstly discussed;performances of KF,EKF and MVEKF algorithms are thoroughly analyzed according to simulation results,which will be helpful to engineering applications. |
