关于三相三电平逆变器IGBT的一个仿真模型(On the three phase three level inverter IGBT a simulation model)

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)

《kalman滤波理论及其在导航系统中的应用》,对卡尔曼滤波在导航中的应用有很好的指导作用("Kalman" filter theory and its application in navigation system, a very good role in guiding the application of Calman filter in the navigation)
