摘　　要：利用仿真生成的二维辐射场景数据,提出了一种探测系统性能的评估分析方法,建立了美国天基红外高轨探测系统(SBIRS-H)总体指标与探测性能的关系。该方法以统计的杂波等效目标定量描述了场景杂波大小,并利用信杂比综合表征探测性能,反映出不同系统参数下的探测性能变化规律,可应用在红外探测系统方案分析、设计与评估阶段。An evaluation and analysis method for space-based infrared system （SBIRS-H）performance is proposed based on the simulated radiation scene data.The relationship between overall specifications of detection system and detection performance is built.The scene clutter is quantitatively described by introducing the clutter-equivalent-tar-get.The signal-to-clutter ratio is used to characterize the integrate detection performance,and this method can reflect change rule of detection performance at different parameters.The proposed method could be applied for the analysis, design and evaluation of the infrared detection system.
