雷达和ESM相关的仿真研究

雷达和ESM航迹关联可以认为是模式识别问题。在统计假设检验理论和模糊综合分析基础上建立了多目标运动模型、多门限数学模型、时序关联决策模型，给出了累积数据快速计算的模型，以此可对两类传感器的观测数据进行在线时间校准。通过模型能够实现雷达和ESM的快速关联，满足航迹关联的精度要求，并对不同运动态势的关联结果进行分析比较，取得了满意的结果。

Simulation Research on Radar-ESM Track Correlation

The problem of radar-ESM correlation can be considered as a pattern recognition problem. The position of target can be ascertained by using the azimuth of target. Based on statistical hypothesis theory and fuzzy synthetic analysis, multi-threshold mathematical model, multi-target motion model and sequence time correlation mathematical model are presented in the paper. Furthermore, a fast correlation model based on accumulative data accounting is proposed by which the measurements of two kinds of sensors can be smoothed and interpolated on-line. The result of fast correlation can meet precision demand in track-to-track fusion. Finally, the simulations of correlation result on different movement situation are analyzed in detail. The analytical results have important reference value to practical application.
