利用多光谱遥感影像进行地物目标识别和提取已经有20多年的研究历史，取得了一定的研究成果，但是已有的地物目标识别提取方法所用到的地物目标的特征信息还比较单一，因此地物目标的识别率和提取效果还不够理想。

Target recognition is vital for hattie.

目标识别成为战争胜败的关键，而对目标识别的关键之一是对目标特征的提取与选择。

As a result,the general threshold judgement of correlation pea k will fail,misrecognition occurs,and the recognition possibility was decreased unavoidably,especially for the multi-target recognition and inter-class target partition tasks.

特别对于多目标识别与不同类目标的区分，常规的相关门限判决方法会造成很大的误识别，大大影响了ATR系统的识别可靠性。

The recognition possibility for intra-class target dis tortion version and misrecognition possibility for inter-class target are two m ain performances of an automatic target recognition system.

对同类目标畸变不变的正确识别率与不同类目标分类误识别率是衡量一个自动目标识别系统的两个最重要性能指标。

Target fusion recognition system is that target information from various resources for submarine is captured, them is inosculated into target attribute, and it accomplishes target recognition automatically.

Firstly, this thesis lucubrates in the method theory of character space and does a lot of experiments and researches in the two steps, character expressing and measure of similarity. Realize the object recognition system based on the character subspace, which adopts the effective and ameliorative means to solve the problems existing in the course of recognition such as illumination and pose estimation, so enhances the robustness of recognition.

首先深入研究特征空间方法原理，并对识别过程中的两个关键步骤：特征表达和相似性度量做了具体实验和研究工作，实现基于特征空间目标识别系统，其中采用了几种有效的改进方法，有效的解决了识别过程中存在的诸如光照以及3D目标姿态估计等问题，提高了识别鲁棒性。

The method is applied for recognizing three-class targets in MSTAR database and the highest correct probability of recognition arrives at 97.51% which is enhanced obviously.

将该方法用于对MSTAR数据中三类目标识别，识别率最高可达97.51%，明显提高了目标的正确识别率。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
