基于方差检测的自适应机动目标跟踪算法

AN ADAPTIVE ALGORITHM ON MANEUVERING TARGET TRACKING BASED ON VARIANCE ESTIMATION

首先建立了机动目标跟踪的系统动态模型和观测模型,在此基础上提出并分析了基于方差检测的状态自适应调整滤波器,针对不加自适应修正的Kalman滤波在机动目标跟踪中的不足,通过仿真验证了基于方差检测的状态自适应调整滤波器的正确性和可行性。

This essay firstly establishes system dynamic model and system measurement model on maneuvering target tracking; secondly, based on the mathimatic model, specifically puts forward and analyses a kind of filter, which can adjust adaptively system state and is based on variance estimation; finally, proves the filter＇s correctness and feasibility, while proves the insufficiency of Kalman filter without adaptive modification on maneuvering target tracking.
