说明：  32个脉冲调制的线性调频连续波发射信号，单目标回波信号中加入了距离时延与多普勒频移信息。数字下变频后再进行脉压与MTD处理从而检测出距离与速度信息。
(Chirp 32 pulse-modulated continuous wave transmit signals, a single target echo signal from the delay and added to the Doppler shift information. MTD frequency pulse pressure and then be processed to detect the distance and speed of digital information down.)
