摘要:

为了更好探测识别与跟踪空飘球,考虑到空飘球运动与环境风的高度相关性,综合应用雷达探测定位、风场反演技术提出一种预测空飘球轨迹并判断其载荷的方法。基于当下主流的速度平面处理方法提出双体积单元风场反演方案。方案中,通过建立空飘球流体力学分析下的动力学模型实现空飘球在空轨迹的预测;引入轨迹惯性度(degree of inertia,DOI)和质阻比计算空飘球空载状态下理论轨迹与实际轨迹的差异,分析其自身空飘属性与携带载荷状况。通过仿真实验验证所提方法,结果表明所提风场反演方法各方向风场反演平均绝对误差在0.1以下,轨迹预测误差小于0.162,且在随机观测误差下展现了较好的鲁棒性;通过DOI值能有效判断空飘球带载有无的情况且判断结果受风场观测误差影响较小,相较于空载状态,载荷质量增加1%时DOI值增加16倍,并能较好表现空飘球与载荷之间的质量分布关系,且当载荷质量占比7%以上时DOI判据更为有效;同时通过DOI值能用于判断空飘球是否具备自主动力,根据仿真结果可以认为DOI值大于202,表明空飘球可能具备自主动力。

Abstract:

To better detect, identify, and track air floating ball, considering the high correlation between the movement of air floating ball and environmental winds, a method that integrates radar detection and positioning, wind field inversion technology to predict the trajectory of air floating ball and determine their payloads is proposed. Based on the current mainstream velocity plane processing method, a dual-volume unit wind field inversion scheme is introduced. In the scheme, a dynamic model with the analysis of aerodynamics for air floating ball is established to predict their trajectories in the air. Additionally, the trajectory degree of inertia (DOI) and mass resistance ratio are introduced to calculate the difference between the theoretical and actual trajectories of air floating ball in an unloaded state, thereby analyzing their inherent aerial attributes and payload conditions. The proposed method is verified by simulation experiments. The results show that the mean absolute error of wind field inversion is below 0.1. The trajectory prediction error is less than 0.162 and it also shows a good robustness with the random observation error. The DOI value can effectively judge the existence of the payload of air floating ball, and the judgment result is less affected by the wind field observation error. Compared to the unloaded state, a 16-fold increase in DOI values with a 1% increase in payload mass. DOI can better display the mass distribution relationship between the air floating ball and the load, when the payload mass accounts for more than 7%, the DOI criterion is more effective. At the same time, the DOI value can be used to judge whether the air floating ball has independent power. From the simulation results, it can be considered that the DOI values greater than 202 indicates that the air floating ball may have autonomous power.

Key words: air floating ball, trajectory prediction, payload recognition, wind field inversion, trajectory degree of inertia (DOI)
