Wavelet transformation is a powerful tool in many areas of research. This paper discusses the fundamental theory of wavelet transformation and its applications in analysis of random errors of radar measurement data, including the principle and process of denoising using wavelet transformation and calculation of variance using modified MAD algorithms. Simulation shows that wavelet transformation is effective and convenient to implement, and it is of high significance in real world applications.
