【摘 要】目标识别能力是武器装备系统作战能力研究的重要内容，对武器装备的发展具有一定的指导意义。提出了目标识别能力的指标体系结构，重点分析了目标识别过程的目标检测能力、目标分类能力和目标确认能力等3种能力的性能指标，并研究了指标的计算或统计方法。该项研究丰富了目标识别能力指标的理论方法，可用于指导武器装备系统的性能评估工作，有效提高系统的综合作战能力。%Target identification capability is a major rearch aspect of weapon systems' combat capability, the re-sult of what can be ud to direct the development of the weapon and equipment. This paper propos the structure of target identification capability index and primarily analyzes three capabilities' index of target recognition process, including target detection capability, target classification capability and target confirmation capability. Then, com-putation or statistic method of the index is given. This study enriches the theories and methods of target identifica-tion capability and can be ud to guide effectiveness evaluation of weapon systems and improve the combat capabil-ity of systems.

1 Introduction
生物手抄报初一Weapon systems are esntial for national defen.They are concerned by different countries’military more and more.What is weapon system?All weapons of the army;weap
ons ud in some battle;even one naval vesl or combat aircraft.To rearch weapon equipment system，the first is to rearch its effectiveness.One method is rearching system’s combat capability firstly，and then computing combat effectiveness bad on input variable of combat capability ［1］.Sometimes，combat capability and combat effectiveness are confud by more rearchers，such as an author thinks equipment’s combat capability equals to combat effectiveness in its book ［2］.Another author defines combat capability as the combination of combat effectiveness and command effectiveness［3］.The author of Reference［4］rearches combat effectiveness’s evaluation methods and its supporting technology systematically.Combat capability is the“skill”of weapon equipment in systematology，which is a static concept and unrelated to combat process.But combat effectiveness is a dynamic concept and the effect of combat capability.
Combat capability is a broad concept and different weapons have different capabilities.But target identification capability is a public capability of all weapon systems.Many authors discuss index of target identification in their treatis［5－6］.He
come的反义词Jun and his team survey measures of ATR performance evaluation［6］，including confusion matrix，probability index，rate index and ROC index;however，they do not construct index frame.This paper mainly concerns capability index of weapon systems，discuss definition of target identification and its hierarchy nexus，and then constructs and analyzes target identification capability’s index framework.
2 Basic Concept of Target Identification
Target identification，the basic concept of which is some discrimination of target such as target attribute and its state，belongs and develops to mode identification.According to number of data sources，target identification is distinguished to single source identification and multisource identification.The former us target signals acquired by nsors to process and identify target attribute or state.The latter combines multisource data and then identifies target’s identity(ID)bad on prior knowledge.Commonly，weapon systems identify target’s attribute including model，type，friend－orfoe，military or civil u，nation and so on.Target’s state defines as target motion state specially.

3 Identification Capability Index Framework
Generally，in the combat process of weapon equipment system，target identification can be divided into three stages，which are target detection，target classification and target confirmation.Aiming at every stage，this paper analyzes its capability and constructs capability index，then synthesizes index of three stages to form target identification capability index framework of weapon systems.家长教育孩子经验分享
(1)Target detection stage.Relying on field signals，images and other features acquired by nsors，weapon systems detect potential targets from environment noi.
(2)Target classification stage.Weapon systems extract target features(signal features，image features，or others)and match with features in the databa.Sometimes，arch strategy and matching algorithm are ud to classify targets.The final purpo is to judge target’s type，category or friend－or－foe.
(3)Target confirmation stage.In this stage，weapon systems must extract target’s fine features，and then confirm target’s ID.
Figure 1 gives weapon equipment system’s target identification capability index frame，which includes target detection index，target classification index and target confirmation index.In addition，any weapon system must consume some resource to reach some kind of identification capability.Therefore，cost index of identification system is added to the index framework.

3.1 Target Detection Capability Index
Target Detection Capability Index includes confusion matrix，ROC curve，detection probability and fal alarm probability.The indexes reflect identification capability of weapon systems from background noi from different aspects.
