局部放电试验所采集的信号中往往混有白噪声、周期干扰信号去除。此处采用常用db系列小波中的db6小波进行9尺度的多分辨分解后，根据白噪声能量特性，估算各尺度的阈值大小，采用硬值进行处理，后进行重构。(Partial discharge test of the signal collected is often mixed with white noise, periodic interference signal removal. Here the use of commonly used wavelet db Series DB6 wavelet carried out in the 9-scale multiresolution decomposition, based on the energy characteristics of white noise to estimate the scale threshold size, the use of hard-value deal, after the remodeling.)

相位梯度自聚焦算法（PGA）的matlab程序实现，合成孔径雷达中最经典最常用的自聚焦和运动误差补偿方法(The phase gradient autofocus algorithm (PGA) of matlab implementation, the most classic of the most commonly used in synthetic aperture radar self-focusing and the motion error compensation method)
