摘要
高光谱卫星效能评估是高光谱遥感卫星发展的重要内容,对高光谱遥感卫星设计、研制和在轨性能监测具有很强的现实意义。效能分析与建模是开展高光谱遥感卫星效能评估工作的第一步,针对此问题,首先介绍典型星载高光谱遥感成像仪,其次解析高光谱目标检测效能指标,并且深入分析影响高光谱遥感卫星舰船目标检测效能的关键因素。同时,对舰船目标检测效能的影响因素进行量化,以目标发现概率为例,构建目标检测效能模型框架,并且采用两种公开的舰船目标数据集分别开展实验分析与模型验证,表明了模型构建的合理性及有效性,对高光谱卫星舰船目标检测效能评估具有重要意义。
The effectiveness evaluation of hyperspectral satellites is an important part of hyperspectral remote sensing satellites development,holding significant practical implications for their design,development,and in-orbit effectiveness monitoring.Effectiveness analysis and modeling serve as the initial step in conducting an effectiveness evaluation of hyperspectral remote sensing satellites.To tackle this issue,firstly,typical spaceborne hyperspectral remote sensing imagers is introduced.Then,the effectiveness indicators for hyperspectral target detection is dissected and a deep analysis of the key factors is conducted that influence the effectiveness of hyperspectral satellite-based ship target detection.Meanwhile,the factors that impact the effectiveness of ship target detection are quantified.Taking the target detection probability as an example,a framework for the target detection effectiveness model is established.Subsequently,experimental analysis and model validation are performed using two publicly available ship target datasets,respectively,demonstrating the rationality and validity of the constructed model.This work holds significant importance for evaluating the effectiveness of hyperspectral satellite-based ship target detection.
