说明： 3) 跨平台文档结构的调整 项目文档是始终贯穿着整个系统的，但由于Windows系统与其他系统如Linux等的文档结构不同，项目的可移植性将会受到限制，因此强调可移植性的本系统中跨平台文档结构的调整是必不可少的，我们预计在这一阶段以Windows 和 Linux为基础出2套相应的代码版本，基础代码部分不变，只是在文档接口及对应的应用工具上做出相应的选择。预计所需时间为二个月，包括平台的移植，接口的研究和开发等(3) cross-platform document the restructuring of the project document is always run through the whole system, but the Windows system and other systems such as Linux and other documents of different structures, the project will be subject to the portability restrictions of the emphasis on portability cross-platform file system structure is essential, we expect at this stage in Windows and Linux based on the 2 versions of the corresponding code, the basis of some of the same code, but in the document application interface and the corresponding tools choices accordingly. Expected time required for months, including platform migration, interfaces, such as research and development)

用新的高级加密标准（AES）保持你的数据安全
AES（The Advanced Encryption Standard）是美国国家标准与技术研究所用于加密电子数据的规范。它被预期能成为人们公认的加密包括金融、电信和政府数字信息的方法。本文展示了AES的概貌并解析了它使用的算法。包括一个完整的C#实现和加密.NET数据的举例。在读完本文后你将能用AES加密、测试 基于AES的软件并能在你的系统中使用AES加密。 (AES (The Advanced Encryption Standard) is the National Institute of Standards and Technology for electronic data encryption standards. It was expected to be recognized by encryption including financial, telecommunications and government of digital information. This paper showed a picture of AES and its use of analytic algorithm. Including a complete C# and encryption.NET data, for example. After reading this you will be able to use AES encryption, AES-based testing and software in your system to use AES encryption.)

介绍了经典的时频分布和检测理论的同时，作者利用时频分布的方法，将一
维时间信号转化到二维的时频空间中，通过提取图像的特征来判决信号和杂波，
采用的数据是使用McMaster IPIX雷达，在加拿大东海岸附近测得的。实测数据
研究表明此方法可以得到很好的检测结果。
(In this paper,we first review the time-frequency analysis and time
-frequency-based detection methods.Secondly,by analyzing a mass of the measured
data of sea clutter,we show the difference of time-frequency geometric features
between echoes with a target and pure sea clutter.Finally,we given the detection
algorithm based on the time-frequency geometric features.The results of the measured
data show that the proposed method can effectively find low-velocity small targets in
sea clutter.This approach is a novel try to detect small targets in sea clutter.)
