摘　　要：在使用交叉条形(XS)阳极单光子探测器进行空间目标探测的过程中,会产生大量的混叠数据,而这些数据却无法被直接使用。为了提高目标定位的速度和质量,需要提高数据的利用效率,对混叠数据进行合理利用。对探测过程中产生的混叠数据进行建模和分析,得到了混叠数据的具体数据结构,并提出保留混叠数据的质心探测方法。设计了数值仿真和实际光路实验,将保留和去除混叠数据两种方法的探测结果进行对比。在仿真和实验中,保留混叠数据的方法均获得了更低的探测误差。在实验中,保留混叠数据方法比去除混叠数据方法的探测误差平均降低了11.9%,可以得到更为准确的探测结果,实现更加快速、高效的目标定位。When using cross-strip(XS)anode single-photon detectors for space target detection,a substantial amount of aliased data is generated,which cannot be directly utilized.To improve the speed and quality of target localization,it is crucial to improve data utilization efficiency and effectively use aliased data.This involves modeling and analyzing the aliased data generated during the detection process,understanding the specific data structure,and using a centroid detection method that preserves the aliased data.In this study,we performed numerical simulations and actual optical path experiments to compare the detection results of methods that retain versus those that remove aliased data.In simulation and experimental settings,the method retained aliased data achieved lower detection errors.In experiments,retaining aliased data reduced the detection error by an average of 11.9%compared to the case of removing it,resulting in more accurate detection and faster,more efficient target localization.
