【摘要】 为有效构建海洋目标探测卫星体系,建立一套能对各类卫星的海洋目标探测效果进行分析与评估的通用效能模型非常重要。初步建立了以目标探测概率为度量的海洋目标探测卫星通用效能模型,可用于光学成像、雷达成像和电子侦察卫星等。模型考虑了影响目标探测概率的三类主要因素即观测区域与目标特性、卫星平台参数和卫星有效载荷特性,分析了卫星技术性能指标和作战性能指标的相互关系,可作为海洋目标探测卫星体系需求分析、顶层设计以及效能评估的依据。并以大型舰船为探测目标用仿真结果说明了模型的适用性。更多还原

【Abstract】 To build the ocean target detection system effectively,it is very important to build a set of general effectiveness model which can be used to analyze and evaluate various ocean target detection satellite system.The general effectiveness model of the ocean target detection satellite system is built,which takes the target detection probability as the main measurement and can be used to photo-imaging,radar-imaging and electronic-reconnaissance satellite,etc.The model takes into account the three main factors which affect the target detection probability,i.e.,the characteristics of the detection area as well as the detection target,the satellite platform and the payload,and analyzes the relationship of the between the technical index and the tactical index,and can be used in the requirement analysis,system design and effectiveness evaluation of ocean target detection satellite system.The simulation results are also given to illustrate the applicability of this model.更多还原
