从信号处理的角度讲，小波(变换)是强有力的时频分析(处理)工具，是在克服傅立叶变换缺点的基础上发展而来的，所以从信号处理的角度认识小波，需要傅立叶变换、傅立叶级数、滤波器等的基础知识。 (From signal processing perspective, the wavelet (transform) is a powerful time-frequency analysis (processing) tool is to overcome the shortcomings on the basis of Fourier transform evolved, so from the perspective of understanding of wavelet signal processing need to Fourier transform, Fourier series, filters and other basic knowledge.)

雷达系统仿真，采用相位编码脉内线性调频混合调制信号。该雷达具有数字化正交解调、脉冲压缩处理、固定目标对消、动目标检测（MTD）、和恒虚警（CFAR）处理等功能(Radar simulation system，using the LFM and barker code mixed modulated signal。Main function include：digital orthogonal demodulationfixed, Pulse compression，target cancellation, moving object detection (MTD), and the constant false-alarm (CFAR) processing etc)
