基于Roberts直线表示的三维空间约束航迹起始算法
A Three-Dimensional Space-Constrained Track Initiation Algorithm Based on Roberts'Straight-Line Representation
摘要
Abstract
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.关键词
