N2 - Optical imaging satellite constellation (OISC) can provide imagery products with optimized coverage performance and high temporal resolution than single satellite, and is widely used in target detecting and analysis. People highly concerns with the performance in target identification of OISC during observation missions, so it is necessary to evaluate the target characteristics (TC) detecting capability of satellite constellation. Based on Analytic Hierarchy Process (AHP), a detection capability evaluation method for OISC is presented in terms of TC in this paper. A hierarchical structure is established to demonstrate the affiliation of indexes concerned with TC and capability of OISC. After that, weight coefficient of each index is computed using AHP. Moreover, we put forward quantitative method to normalize performance indexes of OISC, and calculate the evaluation result by linear-weighted summation method. At last, Jilin-1 Constellation, Zhuhai-1 Constellation, etc., are evaluated with the method to test its feasibility.
