基于曲线拟合分析的空中目标运动样式识别

Moving Type Recognition of Air Target Based on Curve Fitting Analysis

提出了一种基于曲线拟合分析的空中目标运动样式识别方法。首先分析了目标运动样式与平面曲线间的表征关系,提取了识别特征,再用最小二乘法对目标轨迹进行曲线拟合和处理,提取运动特征并与识别特征比较,得到目标运动样式,最后通过实例分析进行验证。结果表明所提方法的识别结果与真实情况一致,证明了该方法的有效性。

This paper proposes a method to recognize the moving type of air target based on curve fitting analysis,firstly analyzes the representation relation between target moving type and plane curve,extracts the recognition characteristic,then performs curve fitting and processing to the target track by means of least square procedure,extracts moving characteristic of the target,and compares with recognition characteristic to obtain the target moving type,finally validates the method through the analysis of actual case.The results show that recognition result of the proposed method in accordance with the real situation,which proves the effectiveness of the method.
