Particle filtering is an non-parameterized algorithm via sequential Monte Carlo simulation to actualize bayesian estimation. This paper expatiated the development and the research status of particle filtering at present.Then,introduces and analyses the principle of particle filtering、the existed key problems and countermeasures in detail.Furthermore,it sum up eleven improved methods of particle filtering algorithm.Meanwhile,applications are addressed in this paper.Finally ,the prospect of particle filtering is presented.

这是一个非常重要的而又简单的程序，是书上常用和数学建模的好帮手(great partner)

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.)
