从解决目标跟踪中的非线性问题入手,分析了不同的解决方法,并结合地面红外搜索跟踪(IRST)系统单独使用时的实际特点,提出了球面坐标降维模型,给出了相应的目标纯角度跟踪算法。目标状态方程和量测方程得到了简化。最后进行了目标跟踪的仿真试验,结果表明这种纯角度跟踪算法具有很好的性能。

The different solving methods are analyzed starting from thenonlinear problem in Target Tracking(TT). A spherical coordinate descending dimension model is proposed by combining with the practical characteristics when ground-based IR search tracking system is singly applied. A corresponding target angular-only tracking algorithm is given. Both target status equation and measurement equation are simplified. Simulation testing for target tracking is carried out in the end. The simulation results show that the angular-only tracking algorithm has good performances.
