A Passive Location Algorithm for Airborne Observer Based on UKF
Pages: 13-16,41
Year: Issue:  5
Journal: AEROSPACE CONTROL

Keyword:  无源定位卡尔曼滤波器非线性;
Abstract: 提出了一种基于UKF(Unscented Kalman Filter)的机载无源定位算法,并结合应用背景,对系统模型以及通常的UKF算法作了相应的改进.该算法对量测模型非线性问题采用UKF予以解决,克服了EKF(Extended Kalman Filter)中引入的较大线性化误差对性能的影响.与基于EKF的定位算法相比,本文提出的算法滤波性能更好,对初始估计误差不敏感,并且算法不用计算雅可比或黑赛矩阵,更容易实现.仿真结果验证了提出算法的优越性.
