基于IEC61131—3标准的连续定位运动模块MC—PositionProfile，可以使用户方便的定义几点，然 后实现加速度平滑变化的运动。虽然其保证了加速度的平滑过渡，但没有考虑轴会发生反转，本文讨论的是 在保证加速度变化平滑的基础上实现轴的单向运动。(IEC61131-3 standard based on the continuous positioning movement module MC-PositionProfile, allows the user to easily define points, and then change to achieve smooth acceleration of the movement. Although its acceleration to ensure a smooth transition, but did not consider the axis will be reversed, this discussion is to ensure the smooth acceleration on the basis of changes in one-way movement axis.)

说明：  该程序展示出了多普勒压缩系数与距离之间的关系，也即显示出了单频矩形脉冲的距离分辨力。(The program demonstrates the Doppler compression factor and the distance between them and also that showed single-frequency rectangular pulse range resolution.)

This tutorial is designed to give the reader an understanding of Principal Components Analysis (PCA). PCA is a useful statistical technique that has found application in fields such as face recognition and image compression, and is a common technique for finding patterns in data of high dimension. Before getting to a description of PCA, this tutorial first introduces mathematical concepts that will be used in PCA. It covers standard deviation, covariance, eigenvectors and eigenvalues. This background knowledge is meant to make the PCA section very straightforward, but can be skipped if the concepts are already familiar.
