正交匹配追踪算法(OMP)是一种利用一个超完备的字典进行信号分解的非线性自适应算法(Template matching matlab program)

说明：  随着信息容量的增加和频率资源的稀缺，为提高单位频带利用率，在微波通信系统中越来越多地采用多电平多相位的复杂信号调制方式，尤其是正交幅度调制(QAM)得到了大量的应用，从早期的4QAM到今天的16QAM。高阶QAM调制大容量数字微波通信系统为了保证服务质量，降低误码率，(long with the increase of information capacity and frequency resource scarcity, for improving the utilization ratio, unit of microwave communication bandwidth used more and more in the system of multilevel much phase modulation method complex signal amplitude modulation )

物理光学方法 近似计算散射体RCS POFACETS is an implementation of the physical optics approximation for predicting the radar cross section (RCS) of complex objects. It utilizes the scientific computational features of MATLAB and its Graphical User Interface (GUI) functions to provide an error-free encoding of input parameters and efficient calculation of RCS. POFACETS provides a convenient tool for a “first cut” at the RCS of complex shapes by representing its constituent parts by triangular facets. The software calculates the monostatic or bistatic RCS of the object for the parameters specified(POFACETS is an implementation of the physical optics approximation for predicting the radar cross section (RCS) of complex objects.
