Abstract
Target Characteristic (TC) detection capability evaluation is a hotly studied topic due to its importance in the development of Optical Imaging Satellite (OIS). In this paper, we propose a method to evaluate the OIS-TC detection capability. We use Analytic Hierarchy Process (AHP) to build an Optical Imaging Satellite Target Characteristics Detection Capability Evaluation Index System (OIS-TC-DCEIS). Based on this system and the evaluation of expert, we obtain Weight Coefficient (WC) of Satellite Performance Parameter (SPP). And then, we nondimensionalize physical values of SPPs to get the Evaluation Index Values (EIV). During the process of obtaining the WC and EIV, we use experts’ experience as a reference. After that, we construct an evaluation equation to calculate the OIS-TC detection capability by using WC and EIV. As an example, we use this method to evaluate the TC detection capability of SJ-9 satellite and GF-2 satellite.
