付里叶变换的频移特性；付里叶变换的时域卷积特性(Fourier transform of the frequency shift characteristics the Fourier transform of time domain convolution properties)

气象雷达的仿真与分析，为研究机载雷达的工程人员提供真实有效的理论分析与仿真(Modern estimation theory and artificial intelligence technology are applied to the Wind Shear Safety Advisor, a conceptual airborne advisory system to help flight crews avoid or survive encounter with hazardous low-altitude wind shear. Numerical and symbolic processes of the system fuse diverse, time-varying data from ground-based and airborne measurements. Simulated wind-shear-encounter scenarios illustrate the need to consider a variety of factors for optimal decision reliability. The wind-shear-encounter simulations show the potential of the Wind Shear Safety Advisor for effectively integrating the available information, highlighting the benefits of the computational techniques employed.)

说明：  一个4阶的切比雪夫Ⅰ型低通滤波器，可以用它对信号进行滤波。当然，滤波器的零极点图也是必不可少的。(A 4-order Chebyshev low-pass filter of type Ⅰ, you can use it to filter the signal. Of course, the filter pole-zero map is essential.)
