基于单站测量的纯仰角目标参数航迹滤波方法

Algorithm to estimate the parametric trajectory of elevation-only target by single station observation data

根据特殊战场环境下传感器测量目标的不完全信息的情况,提出了空间目标纯仰角参数的处理思想,并给出了一种基于投影关系的参数航迹滤波方法,该方法基于斯特瓦尔特定理和总体最小二乘法,讨论了等高飞行目标的纯仰角处理形式和斜直线目标的纯仰角参数滤波形式。仿真验证了该方法能较好适应特殊战场环境下的不完全测量信息情况。

Aiming at the incomplete metrical information of target under special condition of battlefield, a novel pro-cessing idea with the elevation-only parameter is proposed, and a filtering algorithm of parametric trajectory of special target with projection rules is designed. By using Stewart Theorem and Total Least Square Algorithm, the elevation-only filter algorithm is discussed which is under the condition of constant altitude flight and diagonal line flight. The simulation results show that the new algorithm achieves a favorable filtering precision, which can be used under the special condition with incomplete metrical information.
