MATLAB是一种用于科学工程计算的高效率高级语言。MATLAB的基本数据单位是矩阵，它的工具箱已经延伸到了科学研究和工程应用的许多领域。它在诸如一般数值计算、数字信息处理、系统识别、自动控制、振动理论、时序分析与建模、优化设计、神经网络控制、动态仿真系统、金融管理、小波分析、特殊函数和图形领域表现出一般高级语言难以相比的优势，并可以方便地用于几乎所有的科学和工程计算的各方面。(MATLAB is a science and engineering computing for efficient high-level language. MATLAB' s basic data unit is the matrix, and its toolbox has been extended to scientific research and engineering applications in many fields. It is in such general numerical calculation, digital information processing, system identification, automatic control, vibration theory, time series analysis and modeling to optimize design, neural network control, dynamic simulation system, financial management, analysis, special functions and graphics in the field show generally difficult to match the advantages of high-level language, and can be easily used in almost all scientific and engineering computing aspects.)

EMD可以对振动噪声信号分解成多个本征模函数，可以进行时频分析(Time frequency analysis of EMD)

强力推荐ISAR转台成像程序，发送线性调频波。ISAR成像在进行了平动补偿之后，模型等效为转台模型(The ISAR turntable imaging program is strongly recommended, and the LFM wave is transmitted. After the ISAR imaging is compensated for translation, the model is equivalent to a turntable model)
