Extended Kalman Filter Tracking Object in 3-D(Assume that we want to track an object moving in 3-D space with constant velocity. Our instruments observe bearing, range and high(cylindrical coordinates). However, of an interest are rectangular coordinates. Since transformation is non-linear this requires use of extended Kalman filter. Because transformation is non-linear between X,Y and Range,Bearing and linear between Z and high(Z is height), this problems serves as a good comparason of how well extended Kalman filter can perform. By comparing its linear estimation error in Z to non-linear estimations in X and Y, we can judge how non-familiarities effect estimation. )

s变换，是当前比较流行的时频分析算法，可以用于地震数据时频分析和频谱分析，该程序基于matlab平台，实现了s变换和反变换。(s transformation, is the more popular time-frequency analysis algorithms, can be used for seismic data analysis and time-frequency spectrum analysis, the program based on matlab platform realize the s transform and inverse transform.)
