The Porter stemming algorithm (or ‘Porter stemmer’) is a process for removing the commoner morphological and inflexional endings from words in English. Its main use is as part of a term normalisation process that is usually done when setting up Information Retrieval systems.

说明：  挠性转子的平衡原理是建立在弹性轴（梁）横向振动理论的基础上，其动平衡原理为：挠性转子在任意转速下回转时所呈现的动挠度曲线，是无穷多阶振型组成的空间曲线，其前三阶振型是主要成分，振幅较大，其他高阶振型成分振幅很小，可以忽略不计。(Flexible rotor balancing principle is based on the elastic axis (beam) on the basis of transverse vibration theory, the balancing principle is: flexible rotor turning at any speed when the deflection curve presented is composed of infinite number of vibration modes space curve, the first three modes is the main component, the larger the amplitude, the amplitude of the other components of higher modes is very small, can be ignored.)

对机载SAR系统点目标进行模拟仿真，利用RD算法分别对零斜视角、小斜视角、大斜视角进行成像。(This experiment is for point target simulation of SAR system, and we use RD algorithm to achieve point target imaging, respectively, zero oblique angle, a small oblique angle,and a large squint angle imaging.)

this program is for on-off-keying signalling modulation.
