将所有点分成三部分，并在这三部分中分别找到重心-Is divided into three parts, all point to find the center of gravity in three parts

这是关于目标定位的几种基本算法，包括质心算法、RRSI算法、TOA算法、AOA算法，所有程序均已调通，仿真结果通过。-This is some basic algorithm about target positioning,including barycenter ,RSSI,TOA,AOA algorithm,and all of them were tested successfully!

利用频谱线的能量重心原理完成对非整周期采样信号的频谱的幅值和相位的校正。(The amplitude and phase correction of the spectrum of the non periodic sampling signal is completed by using the energy barycenter principle of the spectrum line.)
