多雷达数据融合的整体相关方法

Total-Association Method of Multi-Radar Data Fusion

为解决传感器量测中随机性和模糊性带来的关联错误问题,提出一种整体相关的航迹关联方法。引入模糊集合理论,同时考虑航向、航速、回波幅度等物理量对航迹相关的对应关系,确立了点迹-点迹相关或点迹-航迹相关的处理规则。仿真结果表明,整体相关算法是一种有效的数据关联方法,相关效果良好。

Multi-radar data fusion was a typical system of multi-sensor information fusion and track correlation was one of key technology. Integral-correlation technology was proposed. Its foundation of application was fuzzy set theory, and the error correlation from sensor＇s measure error and uncertainty was solived. The processing rules was given for plot-plot correlation or plot-track correlation. The simulation results showed that this method was an effective data-correlative method.
