Horn_Schunck_Optical_Flow_Method，值得学习(Horn_Schunck_Optical_Flow_Method, worth learning)

逆合成孔径雷达发射信号，通过对观测目标反射的回波进行数据处理，分离出目标的图像信息，从而对目标进行成像( ON划词翻译ON实时翻译 Inverse synthetic aperture radar transmitted signal, data processing by the reflection observation of target echo, separating the image information of the target, so as to image the target)

周期图法在雷达信号处理、目标检测、以及目标跟踪中有重要作用。他的主要特点为从噪声中将所需要的周期信号的特征以功率谱的形式表征出来，通过设置合适的阈值可以代表目标。调频信号则是典型的脉冲压缩信号，其扩频特性使得其不易受噪声干扰。(Periodogram in radar signal processing, target detection, and target tracking plays an important role. His main characteristics will be required from the noise characteristics of periodic signals in the form of the power spectrum characterized it, by setting the appropriate threshold may represent the target. FM signal is a typical pulse compression signal, the spreading characteristics make it less susceptible to noise interference.)
