jakes_model
使用Jakes所假设的模型，用来产生信道抽头延迟线模型中的抽头增益过程所需的多普勒频谱成形滤波器有多种实现方法。时域FIR滤波器是最常用的一种实现方法。(Assumed the use of Jakes model, used to generate the channel-tap-tap delay line model of the process gain the necessary Doppler spectrum shaping filter has a variety of implementations. Time domain FIR filter is an implementation of the most commonly used method.)

第一次作业_基于分类算法的雷达状态识别
第一次作业_基于分类算法的雷达状态识别
对于本数据集中的雷达状态识别，数据降维前使用朴素贝叶斯、支持向量机、神经网络的分类算法对于识别的准确率无太大影响；数据降维后使用神经网络算法最优，支持向量机算法其次，朴素贝叶斯算法较差。此外，训练样本越多，分类准确率有小幅度提高。(First Operation Radar State Recognition Based on Classification Algorithms For radar state recognition in this data set, the classification algorithm of Naive Bayesian, Support Vector Machine and Neural Network before data dimension reduction has little effect on the accuracy of recognition; Neural Network algorithm is the best after data dimension reduction, Support Vector Machine algorithm is the second, Naive Bayesian algorithm is the worst. In addition, the more training samples, the smaller the classification accuracy.)
