说明：  本程序在c平台下开发，描述了awng信道下QPSK调制的方针。结果较为理想(The program developed in c platform described awng channel QPSK modulation approach. More satisfactory results)

这是Bassem R. Mahafza" Matlab Simulations for Radar Systems Design "的书还有它的Matlab的程序。(This is Bassem R. Mahafza s book "Matlab Simulations for Radar Systems Design" with Matlab codes.You have to put the codes on the Matlab folder that you can excute it.)

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. )
