激光雷达是以发射激光束探测目标的位置、速度等特征量的雷达系统。从工作原理上讲，与微波雷达没有根本的区别：向目标发射探测信号(激光束),然后将接收到的从目标反射回来的信号(目标回波)与发射信号进行比较.本程序为FMCW激光雷达matlab程序，包括调频非线性校正等(Laser emitting a laser beam radar detection is the target position, velocity, volume and other characteristics of the radar system. From the working principle, and there is no fundamental difference between the microwave radar: transmitting to the target detection signal (laser beam), then the received signal reflected from the target (target echo) is compared with the transmitted signal, after appropriate treatment , you can get information about the target, such as the target distance, direction, altitude, speed, attitude, and even the shape and other parameters to the aircraft, missiles and other target detection, tracking and identification. This program is FMCW laser radar matlab procedures, including FM nonlinear correction.)

说明：  DEAP 数据库 EEG_feature.txt 包含了1216个脑电信号样本的160维特征，每行为一个样本，每列为一种特征。特征从左至右分别是每个脑电电极的theta（1-32列）、slow alpha（33-64列）、alpha（65-96列）、beta（1-97128列）、gamma（129-160列）波段的脑电特征。 subject_video.txt 包含了1216个脑电信号对应的32名被试和38段视频信息，其中包含两列。第一列是对应的被试编号，第二列是对应的视频编号。 EEG_feature.txt 与 subject_video.txt和valence_arousal_label.txt中每行都是一一对应的，例如subject_video.txt的第二行就是EEG_feature.txt中第二个样本（第二行）的被试和视频信息；valence_arousal_label.txt的第二行也是EEG_feature.txt中第二个样本（第二行）的愉悦度和唤醒度标签。valence_arousal_label.txt中第一列为愉悦度标签，1代表positive，2代表negative；第二列为唤醒度标签，1代表high，2代表low。 DEAP数据库并未提供情感类别标签。(EEG dataset, including DEAP database and MAHNOB-HCI database)
