By using these matlab codes one can generate any noise with mean X and variance Y . Useful for analysis of signals in noisy environment

声波波动方程数值模拟。地震的一个小程序。适合初学者看看。大神就不用下了(Numerical simulation of the acoustic wave equation. Earthquake a small program. Suitable for beginners to see. God would not have got big)

雷达信号处理中MTI，用FFT实现MTD， 用FIR滤波器实现MTD。 (Radar signal processing MTI, with FFT to achieve MTD.Realize MTD with FIR filter.)
