基于支持度函数的2D雷达目标高度估计方法

Height Estimation Method of 2D Radar Target Based on Support Function

针对2D雷达不能测量目标高度参数的问题,提出了一种目标高度实时估计方法。该方法首先利用两部雷达对同一目标参数测量的冗余信息进行目标高度的初步估计,其次利用支持度函数确定不同雷达组合初步估计高度值参与数据融合的权值,最后利用不同雷达组合初步估计的目标高度值以及参与数据融合的相应权重进行目标高度的融合估计。基于典型算例对所提算法进行验证,结果表明所提算法能够较好地解决目标高度问题,具有一定的理论意义和较好的应用价值。

In the case of the problem that the height parameter of target cannot be measured by 2D radar,a method of real time estimation is proposed.Firstly,the height of target is estimated preliminarily through the redundant parameter information of the same target measured by two radars.Secondly,the weight of preliminary height estimation between different groups of radar is calculated by the support function.Finally,the height of target is estimated on the basis of the fusion weight and the preliminary height estima tion.Typical example is used to validate the proposed estimation method,and the result shows that the height of target can be estimat ed well,and the method has theoretical and practical significance.
