This code is about short time fourier transform.

wavelet小波通用去噪方法，包括几幅雷达图像(General wavelet wavelet denoising methods, including the pieces of radar images)

Aiming at determining the satellite attitude precisely，the gyros bias and m isa lignment were compensated in time by using the quaternion of star-sensor and extended Kalm an filter．The related module of the filter was derived．The theoretic accuracy of the algorithm was acquired from the numerical simulation． The effects of the star-senso r misalignment on attitude determination were analyzed at last．

this codes are not so important but they are useful to learn matlab signal processing
