这是基于IHMPT（积分高阶匹配相位变换）方法的多分量三阶相位多项式信号（即立方相位信号）参数估计算法程序包，包含了相关的6个子函数、测试程序以及参考文献等。可以实现对各分量的幅度、各阶相位系数的精确估计。具有广泛的应用，如雷达成像中回波信号具有多阶相位多项式的形式。(This is a matlab code package for an algorithm of estimating parameters of Multicomponent 3-order Polynomial phase signal (Cubic-PPS). The algorithm is based on IHMPT(Integrated High-order Matched Phase Transform). The code package include relevant functions,test codes and reference paper. An accurate estimation of the amplitude and phase coefficients of each order can be obtained by this package. It has a wide application,e.g., the echo signal of radar has the form of PPS. )
