说明：  在阵列信号处理中,可以对信号的来波方向进行估计,并计算其估计误差!(In array signal processing, the signal can be estimated to wave direction, and calculate the estimation error!)

专门针对matlab中作图方法和GUI的电子书，从基础讲起，适合零基础的初学者。(Specifically for mapping methods and GUI matlab in e-books, basic talk, for zero-based beginners.)

多核变换，稀疏变换，核变换自适应学习，图形图像变换(Description ----------- Multi-Kernel-Path package is a Matlab program that computes the entire regularization path for multiple-kernel learning problems. More precisely, it solves any learning problem with a smooth loss function and where the kernel itself is optimized over combinations of several basis kernels. It returns the solutions for ALL values of the regularization parameter.)

说明：  雷达电子战当中的幅度调制干扰(AM)，频率调制干扰(FM)，相位调制干扰（PM），噪声调制干扰（RM）。也可以很快移植应用于systemVue中的matlab模块之中。(Amplitude modulation jamming (AM), frequency modulation jamming (FM), phase modulation jamming (PM) and noise modulation jamming (RM) in radar electronic warfare. It can also be transplanted into the MATLAB module of systemvue.)

共振解调法诊断轴承损伤类故障的原理概述如下:当轴承某一元件表面出现局部损伤时，在受载运行过程中要撞击与之相互作用的其它元件表面，产生冲击脉冲力，由于冲击脉冲力的频带很宽，必然包含轴承外圈、传感器甚至附加的谐振器等的固有频率而激起这个测振系统的高频固有振动。根据实际情况可以选择某一高频固有振动作为研究对象，通过中心频率等于该固有频率的带通滤波器把该固有振动分离出来。然后进行包络解调，去除高频衰减振动的频率成分，得到只包含故障特征信息的低频包络信号，对这一包络信号进行频谱分析便可以容易地诊断出轴承的故障来。(The principle of resonance demodulation method in the diagnosis of bearing damage such failure overview is as follows: when the bearing surface of a local damage, in the process of loading operation to hit with other elements of the interaction of surface, impact pulse power, due to the impact pulse frequency band is very wide, inevitably contains the bearing outer ring, sensors and even additional resonator and stir up the natural frequency of the vibration system of the high frequency vibration mode.A high frequency vibration mode can be selected according to actual situation as the research object, through the center frequency is equal to the natural frequency of the bandpass filter to separate the natural vibration.Then envelope demodulation, frequency components to remove the high frequency vibration attenuation, get only includes fault feature information of low frequency envelope signal, the envelope signal spectrum analysis can be easily diagnosed bearing failure.)
