说明：  率失真函数是在给定信源和失真度量情况下，求满足保真度准则的平均信息率的极小值。本程序给出了两种特殊情况下的率失真函数的计算(Rate-distortion function is a given source and distortion measure case, seeking to meet the fidelity criteria, the average information rate of the minimum. This procedure presents two special circumstances, the calculation of rate-distortion function)

介绍了某型雷达的目标检测原理, 分析了噪声恒虚警处理中门限系数对目标检测的影响, 提出了一种基于噪声采样的门限系数确定方法, 最后在仿真计算的基础上验证了该方法的可行性。(The constant false alarm rate( CFAR) detection of radar signal plays an important role in radar signal processing. The principle of object detection of a certain radar is introduced, the influence of threshold coeffi􀀁 cient on object detection is analysed, and a method to determin the threshold coefficient based on noise sampling is proposed. Finally, the feasibility of the method is verified through simulation.)

matlab的一些程序的基础，希望对有需要的人有些帮助。(The basis of some programs in MATLAB is expected to be helpful to those in need.)

利用射线追踪法实现地震波场层析成像.在石油行业中,此过程是地震资料应用的一个重要步骤(The use of ray tracing method to achieve seismic wavefield tomography. In the oil industry, this process is the application of seismic data as an important step)

一种基于网格的三角定位算法的文章供大家一起分享(WSN)

这次是添加不同密度的高斯噪声，和上次可做对比。(This is to add Gaussian noise of different densities, and the last to do comparison.)

When the P89LPC90x is in programming mode all pins that are not used for programming are tri-stated. During programming mode the reset pin has a weak pull-up resistor.(When the programming is in a mode 'll pins that are not used for programming are tri- stated. During programming mode the reset pin has a weak pull-up resistor.)
