摘要：
In this study, two scanning methods arc designed by combining photoelectric detection equipment having different apertures. Further, a capability evaluation model is established for the multi-photoelectric detection equipment. The model is simulated and analyzed from the scanning mode, arrangement mode and aperture of the telescope, and the simulation results arc evaluated. The simulation results show that for the selected catalog space debris dataset, the detection results obtained via single-elevation-area scanning arc better than those obtained via multi-elevation-area scanning during the simulation time period. Under the same field of view, the number of debris detected using a combination of four 28-cm-aperture telescopes increases only by 2.4% (single-elevation-area scanning) and 3.6% (multi-elevation-area scanning) when compared with those detected using a 15-cm-aperture telescope combination. The considerably cost-effective 15-cm-aperture telescope combination must be selected to maintain a catalog of the existing space debris, and the 28-cm-aperture telescope combination must be selected for detecting small-sized space debris.
