Lidar has become more and more important recently In FMCW lidar how to generate linear chirped signal is an important issue Besides to improve range resolution a chirped signal with large bandwidth is required In this paper four times chirped bandwidth is achieved using optical injection system and external modulation The error of range testing is around 1~2% witch shows great accuracy and stability in this system
