说明：  利用压缩包内的5和函数产生PPM调制的UWB信号，信号波形为高斯二阶导函数。重复编码次数，TH码长度范围，波形形成参数alpha等参数均可以改变(use compressed within the five functions to generate PPM and the UWB signal modulation, Waveform second derivative of the Gaussian function. Repeat code number, TH code length, alpha waveform parameters such as formation parameters can be changed)

粒子群优化算法 一种经典的启发式算法(Particle swarm optimization algorithm, a classic heuristic algorithm)

适用于三维定位，和chan算法结合使用,能够提高精度。(Very useful.)

在傅立叶变换光学中夫琅和费衍射场的强度分布就等于屏函数的功率谱。因此我们可以直接将光屏进行傅立叶变换，再处理得到衍射图样。(In the Fourier transform optics, Fraunhofer diffraction field intensity distribution is equivalent to the power spectrum display function. Therefore, we can directly Guangping Fourier transform, and then to handle any diffraction pattern.)
