态势估计系统中空中目标航迹仿真模型研究

态势估计系统中,航迹的真实性决定了目标运动行为分析模型的有效性。根据空中目标飞行控制的基本规律,首先建立了空中目标航迹分布的理论模型,并在惯性坐标系中建立了基于随机微分方程的目标运动模型。为了反映空中目标运动状态的统计特性,建立了具有统计特性的空中目标航迹模型。模型综合考虑了各种影响空中目标航迹的因素,并对飞行控制人员的控制行为进行了分析。仿真结果表明该模型能较好反映空中目标的运动行为,能用于态势估计系统模型的检验。

Research on Trajectory Simulation of Air Target in Situation Assessment System

The validity of target kinematics behavior analysis model depends on the facility of target trajectory in situation assessment system.The trajectory theory model of air target was made up according to its basic rule of flight control.A stochastic difference equation to model the air target movement in inertial frame coordinates was introduced.A model with its statistical characteristics was dicussed in order to reflect the statistical characteristics of air target.All the factor that affected target trajectory and the control behavior of flight control staff were considered.The simulation results show that the model can reflect the kinematics behavior of air target and it can be applied in the model test of situation assessment system.
