Description: 从空中水平抛射出的物体，初始水平速度Vx(0)，初始位置坐标(x(0),y(0))；受重力g和阻尼力影响，阻尼力与速度平方成正比，水平和垂直阻尼系数分别为Kx,Ky,；还存在不确定的零均值白噪声干扰力xa和ya。在坐标原点处有一观测设备(不妨想象成雷达)，可测得距离r(零均值白噪声误差r)、角度(零均值白噪声误差)，使用扩展卡尔曼滤波进行仿真。-The level of throwing objects the air, the speed of the initial level of Vx (0), the initial position coordinates (x (0), y (0) g) by gravity and damping force, damping force and velocity is proportional to the square, the horizontal and vertical damping coefficient were Kx, Ky, there are still uncertain zero mean white noise interference force Xa and ya. One observation equipment in the coordinate origin (imagine a radar), can be measured the R (zero mean white noise error angle (R), zero mean white noise error), using the extended Calman filter simulation.

Description: 小波分析、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。-Wavelet Analysis、Signal acquired partial discharge test is often mixed with white noise, periodic interference signal removal. Db series wavelet commonly used here in db6 9 scale wavelet multi-resolution decomposition, according to the energy characteristics of white noise, the estimated size of each scale thresholds, hard-value processing, after reconstruction.
