Aimed to two major problems: one is not decidable and the other is no clear semantics. We construct a framework with explicit representation and formal semantics of goalsgoal description logics, which integrates two types of goals: declarative goals and procedural goals into one concept based on description logics. In addition, the goal plan is defined and analyzed, and some reasoning problems, such as goal consistency and goal satisfiability, are discussed. Contrary to traditional ways of goal description, GDLs can bridge the gap between theory and practice in a natural way.

针对传统的目标描述中存在的不可判定性以及没有清晰的语义等问题，在描述逻辑(description logics，DLs)上，将宣称型和过程型2种类型的目标描述有机地整合在一起，从而构建了具有清晰语义与可判定性的形式化框架--目标描述逻辑(goal description logics， GDLs)，在此基础上，定义了该框架下有关规划规则；建立了可用于判定目标一致性、目标可满足性的方法，与传统的目标描述方法相比，目标描述逻辑为主体领域模型提供了一种更有力的形式化工具，同时为智能主体的模型和设计提供了很好的理论工具。

In this chapter, three kinds of target recognition methods are performed, which are:①Target recognition method based on the description of polarization parameter plane. The echo polarization states of target are projected onto the polarization state plane described by the ellipticity ε and the tilt angle τ of the polarization ellipse, the change of parameter following ferquency becomes the chart. According to the changing trait of the chart, the multidimensional polarization feature space of target has been contructed. Furthermore, a series of polarization feature parameters used in designing the structure of target recognition device are extracted, and they are insensible to the posture of target.②Target recognition method based on the description of Poincare polarization sphere. The echo polarization states of target expressed by Stokes vector are projected onto the Poincare polarization sphere. The conception of polarization ferquency stability, which is used in describing the dynamic distribution characteristics of the target echo polarization states on Poincare polarization sphere, has been defined. A group of polarization feature parameters used in designing the structure of target recognition device are extracted, and they are insensible to the posture of target.③Target recognition method based on the description of frequency sensitivity. In accordance with the conception of the polarization state distance defined on Poincare polarization sphere, the frequency sensibility of the physical structure property of target has been investigated, the frequency distribution feature curves in PSD domain are obtained, and targets'features are extracted by means of the curve-fitting method with Least Square Criterion.

这章具体研究了基于三种极化散射特性描述的相应的目标识别方法：①基于极化参数平面描述的目标识别方法，将目标回波极化状态投影到以极化椭圆参数，即椭圆率角ε和倾角τ表征的极化状态平面上，参数随观测频率的变化就形成了图，根据图的变化特点构造了目标的多维极化特征空间，并提取了不敏感目标姿态变化的极化特征参数组来设计目标的识别器结构；②基于Poincare极化球面描述的目标识别方法，采用Stokes矢量表征目标回波的极化状态，并将其投影到描述极化状态的Poincare极化球面上，定义了极化频率稳定度的概念用以刻画目标回波极化状态在Poincare极化球面上的动态分布信息，提取了准方位不变性的目标极化特征，最后设计了目标的识别器结构；③基于频率敏感性描述的目标识别方法，通过在Poincare极化球面上所定义的极化状态距离的概念，研究的是复杂目标物理结构特性对探测信号频率的敏感程度问题，获得了在极化状态距离下的频率分布特性曲线，采用最小二乘估计曲线拟合方法，它既用于极化特征的降维，同时又直接将拟合参数作为目标的分类特征。
