这是一个贝叶斯独立分量分析(ICA)算法的线性瞬时混合高斯噪声模型和添加剂。解决问题的是ML-II推论,即资源的整合在发现源后和噪声协方差矩阵和混合了最大化的边际似然。充分统计量的估计平均场或变分理论和线性响应修正或通过自适应平均场理论水龙头。平均场方程,解决了信仰传播法的或连续的迭代。(This is a bayesian independent component analysis (ICA) algorithm of instantaneous linear mixed gaussian noise model and additives. The solution to the problem of is ML-II inference, namely of the integration of resources and noise source in found that after the covariance matrices and mixed the maximization of marginal likelihood. Sufficient statistics estimate of the mean field or variational theory and linear response correction or through the adaptive average field theory faucet. Average field equations are solved belief propagation method or continuous iteration.)

改程序为火炮内弹道程序，可以计算气体压力，速度等变化情况(Reform program for the Interior Ballistic program can calculate the gas pressure, speed changes)

说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)

首次提出利用PSO跟踪动态系统 文献[ 36 ]提出用自适应PSO来自动跟踪动态系统的变化,该方法通过对种群中最好微粒的检测和对微粒重新初始化, 有效增强了PSO对系统变化的跟踪能力(PSO is first used to track the dynamic system literature [36] proposed adaptive PSO with dynamic system to automatically track changes in populations by the method of particle detection and the best re-initialization of the particles, effectively enhanced the PSO on system ability to track changes)
