基于Roberts直线表示的三维空间约束航迹起始算法OA
A Three-Dimensional Space-Constrained Track Initiation Algorithm Based on Roberts'Straight-Line Representation
航迹起始是雷达目标跟踪系统中的首要环节.在现代战场复杂的高杂波环境中,现有航迹起始方法的目标航迹起始效率和起始精确度面临严重制约.本文首先根据目标运动学特性构建多层物理约束,通过对雷达点迹的快速筛选有效剔除无效组合,大幅压缩后续处理规模,提升起始效率;其次,为了充分利用三维量测信息,采用了Roberts表示法构建空间直线轨迹的表征模型,将点迹转化为具备抗奇异性的稳定几何特征表达,在此基础上引入修正Hough变换机制,通过参数空间动态聚类实现在强杂波背景下的高效统计累积,以此提高航迹起始率.仿真结果表明,在不同的杂波密度下所提方法与逻辑法和二维Hough变换相比,具有更优的性能.
Track initiation is the primary step in radar target tracking systems.However,in modern battlefields,the high clutter environment significantly limits the initiation efficiency and accuracy of existing track initiation meth-ods.Firstly,this paper constructs multi-layer physical constraints based on target kinematic characteristics.By rapidly screening of radar plots,it effectively eliminates invalid combinations,substantially reduces the scale of subsequent pro-cessing,and enhances the initiation efficiency.Secondly,to fully utilize three-dimensional measurement information,the Roberts representation method is adopted to construct a characterization model for spatial linear trajectories.This con-verts plots into stable geometric feature representations with anti-singularity.Building upon this,a modified Hough trans-form mechanism is introduced.Through random sampling and dynamic clustering in the parameter space,efficient statis-tical accumulation is achieved in the strong clutter background,thereby improving the track initiation rate.Simulation results demonstrate that the proposed method outperforms both the logical method and the two-dimensional Hough trans-form under different clutter densities.
