机载光电传感器视轴指向的智能辅助决策方法

摘要

机载光电传感器视轴应尽可能接近目标线,以缩小指向偏差而不使目标偏离传感器瞬时视场,飞行员在复杂的战场态势下进行视轴操控具有一定困难.针对该问题,提出了一种机载光电传感器视轴指向的智能辅助决策方法,该方法以传感器视轴指向的数学模型为基础,通过专家知识建立引导规则,完成目标与各传感器的配对；计算配对后的各传感器视轴指向偏差和偏差变化率,采用模糊控制算法得出视轴偏移率,引导各传感器视轴指向与之配对的目标.仿真结果表明了该方法能够合理引导各传感器视轴指向目标,并能将视轴指向偏差缩小在很小的范围.%Electro-optical (EO) sensor's boresight direction requires to approach target line so as to reduce the deviation of directivity. An intelligent assistant decision method for Airborne EO Sensor' s Boresight Direction is proposed. By utilizing expert knowledge, the cueing rules are generated to cue each sensor to complete the target-sensor matching process. A fuzzy control algorithm is adopted to lead the matched sensors' boresight. The simulation results indicate that the boresight's deviation of directivity can be limited within a small range while tracking a single target and each sensor can be cued reasonably to extend the tracking time for multi targets.
