matlab经典算法，包括各种绘图制图命令和例子(matlab classic algorithms, including various drawing graphics commands and examples of)

SAR系统信号处理仿真，重信号发射到信号最后处理都有，有四个代码文件，你可以别代开，不需要再加入*.m函数(Simulation of SAR signal processing, signal transmission to signal the final re-processing are, there are four code files, you can do on behalf of the open, no need to add*. m functions)

估计功率谱密度的平滑周期图是一种计算简单的经典方法，其主要特点是与任何模型参数无关，是一种非参数化的方法。(Estimated power spectral density is a smooth periodogram simple classical calculation method, the main feature is not related to any model parameter, is a non-parametric methods.)

说明：  很多matlab例子(many examples Matlab)

介绍了 Cohen类双线性时频分布并针对交叉干扰项影响无法完全消除的问题进行了重排时频变换以提取及分辨 含有白噪声和窄带周期干扰的局部放电信号。处理仿真和现场检测到的局部放电超声信号时根据白噪声和窄带 周期干扰信号在时域上的平稳性特性发现重排 Cohen类时频变换方法不仅可以很好地将局放信号和背景噪声以 及窄带周期干扰信号分辨开来,而且大大减弱并抑制了交叉干扰项的影响,保持了更高的时频分辨率和时频聚集 性,从而验证了重排 Cohen类时频变换方法的有效性。 (In order to express the partial discharge ( PD) information of gas insulated switchgear ( GIS) in time-frequency domain, weintroduced theCohen? s class bilinear time-frequency distribution and its reassigned time-frequency transform method to pick up and distinguish theultrasonic signals in field from the whitenoises and narrow band periodic interference signals using the acousticemission ( AE) technology. After the processing of the simulated and PD ultrasonic signals in field, and according to the stationary feature of white noises and narrow band interference signals, wedraw a conclusion that the reassigned time-frequency distribution method can not only distinguish thePD signal from back ground noises and narrow band interference signals, but also decrease and restrain the influenceof cross-items, and acquire better time )
