摘要
空间近距离巡查可以开展对目标的近距离观测和监视,用于识别目标类型和工作状态等,对在轨服务、博弈对抗等军民领域均具有重要意义。分析了空间巡查任务的一般形式,并以近距离巡查最常用的光学观测为对象,构建了巡查观测的约束模型和相对距离因素评估模型、有效观测时间评估模型、目标观测角度评估模型等多因素的观测任务效能评估模型,解决了面向巡查任务全过程的综合效能评估问题,可以更好地支撑基于评估结果的巡查策略设计和巡查轨迹优化等。基于数值算例分析和半实物仿真实验,对提出的评估模型进行了仿真验证,结果显示实际观测效果和模型评估结果一致。
Space close-range patrol can be used to carry out close-range observation and monitoring of targets for identifying the target′s types and working states,which is of great significance for military and civilian fields such as in orbit services.The study analyzed the general forms of space close-range patrol tasks.Furthermore,based on the optical observations of close-range patrol,the multifactor observation task effectiveness evaluation models were constructed,including a constraint model for observation,a relative distance evaluation model,an effective observation time evaluation model,and a target observation angle evaluation model.This solved the effectiveness evaluation problem for the complete process of patrol tasks,which can support the design of patrol strategies and patrol trajectories better based on the evaluation results.In addition,based on the numerical simulation analysis and semi-physical experiments,the proposed evaluation model was verified.The result shows that the actual observation effect is consistent with the model evaluation result.
