通过利用辛普森二重积分，求解矩形孔菲涅耳衍射，完全正确的代码。(Through the use of Simpson double integral, Fresnel diffraction Rectangular hole completely correct code.)

：本文主要研究了应用多相滤波技术的信道化接收机建模问题。在给定信道频谱划分方案下，推导了基于多相 滤波器的信道化接收机数学模型。并由此模型设计了一个四信道模拟系统。最后用仿真实验结果验证了模型的正确性。(research a wave filter )

该代码为基于灰色神经网络的预测算法，里面数据累加作为网络输入(The code is based on the gray neural network prediction algorithm)

对旧金山海岸的极化SAR数据进行分类。根据图像像素点的散射特性采用Freeman分解对图像进行分类，利用wishart聚类算法聚类。最后得到极化sar数据的分类结果。保证了图像的极化特性和散射特性(Polarimetric SAR data to classify the coast of San Francisco. Freeman decomposition using the image classification, clustering clustering algorithm based on the use of wishart scattering characteristics of the image pixels. The last classification results obtained polarization sar data. To ensure that the polarization characteristics of the image and scattering properties)
