LPFG长周期光纤光栅的模拟仿真，值得参考下载啊(the analog simulation of LPFG is worthy of reference.)

对海杂波的仿真，考虑了相控阵雷达威力范围、随着距离增大而引起的强度衰减、杂波类型、对海杂波的抑制等多个方面，对雷达总体设计人员有一定的帮助，值得学习和借鉴。(simulate sea clutter with consideration of many aspects, such as sphere of action of PAR radar, strength attenuation resulted from extending range, type of clutter and inhibition of sea clutter)

说明：  SAR雷达模拟的PPT，讲述SAR雷达回波模拟的具体原理，实现方法，和仿真结果(SAR)

计算X光机拍出的一幅图像有多少个坏点，就是说可以计算出有多少个像素不正常的点，经过反复验证了的。(How many dead pixels calculated X-ray machine to shoot an image, that can calculate the number of pixels in the normal point, after repeated verified.)

在用遗传算法进行JOBSHOP－SHEDULING时，编写的针对LMAX及CMAX的问题产生程序段。(Using genetic algorithm JOBSHOP-SHEDULING when prepared LMAX and Cmax for the problem of program segment.)

波达方向（DOA） 估计的基本问题就是确定同时处在空间某一区 域多个感兴趣的信号的空间位置(即多个信号到达阵列参考阵元的方 向角)。最早的也是最经典的超分辨率(DOA)估计算法是著名的多信号 分类（Multiple Signal Classification） 法,简称 MUSIC 算法,它是 一类经典的基于特征结构分析的空间谱估计方法。该算法利用了信号 子空间和噪声子空间的正交性,构造空间谱函数,通过谱峰搜索,检测 信号的 DOA。(The basic problem of DOA estimation is to determine the simultaneous location in a certain region of space. Spatial position of multiple interested signals in the domain (i.e. the direction of multiple signals reaching the array reference elements) Directional angle). The earliest and most classical super-resolution (DOA) estimation algorithm is the well-known multi-signal.Multiple Signal Classification, referred to as MUSIC algorithm, is A classical spatial spectrum estimation method based on eigenstructure analysis. The algorithm utilizes signals. The orthogonality of subspace and noise subspace, the construction of spatial spectral function, through peak search, detection DOA of signal.)
