Abstract :
The purpose of this paper is present the relation between Mach-Zehender intensity (MZI) modulator operation and the detection method used in chirped lidar. In addition; we analyze the effect of target velocity on detected signal bandwidth by chirped lidar; this analysis is produced from Doppler frequency is sometimes greater than range frequency in contrast, in conventional CW radar.
