说明：   Direct Sequence Spread Spectrum

在现代谱估计中，用自相关的无偏估计代替周期图中自相关函数的有偏估计，可能导致出现负的谱估计值，因此采用BT谱估计器的方法(In the modern spectral estimation, the use of self-related unbiased estimate the figure to replace the cycle of auto-correlation function biased estimate may lead to a negative estimated value of the spectrum, so the use of BT s method of spectral estimation)

利用Singer模型算法对机动目标进行跟踪，算出X方向量测噪声方差以及y方向量测噪声方差(Singer model algorithm used to track maneuvering target, calculate the X direction of the measurement noise variance and the y direction of the measurement noise variance)

matlab_gui实例讲解，针对于有一定基础的人员学习！(matlab_gui examples to explain, for staff based learning!)

内容为 自适应复高斯雷达目标识别 的Matlab程序。 (Content adaptive reuse Gaussian radar target recognition Matlab procedures.)

利用matlab模拟汽车泊车过程，用plot画出了整个过程(Use matlab simulate car parking process, with plot depicts the entire process)

产生正态变量的随机数,进行未知参数的区间估计 产生两个正态总体的随机数, 进行未知参数均值差,方差比的区间估计.( generate normial variable, estimate unknown paramatric interval )

说明：  this is new approach for fuel cell control.it is really helpfull.
