DOPPLER LIDAR DEVICE CAPABLE OF EXTRACTING MULTIPLE TRANSMISSION LASERS WITH A DIFFERENT WAVE FROM GENERAL LASER SHOT FROM A LASER PART, AND AN OPERATING METHOD FOR A DOPPLER LIDAR DEVICE

摘要

PURPOSE: A Doppler lidar device and an operating method for a Doppler lidar device are provided to sensitively measure the characteristics of a wind field using general laser by obtaining the direction and speed of the wind.;CONSTITUTION: A Doppler lidar device (100) comprises a transmitter (103), a receiver (105), and an analyzer (107). The transmitter extracts each of the transmission lasers with a different wave from laser shot from the laser part and irradiates the extracted transmission lasers on an object in different directions. The receiver receives scattered signals which are backscattered from the object corresponding to the transmission lasers. The analyzer obtains information on the object using the received scattered signals.;COPYRIGHT KIPO 2013;[Reference numerals] (101) Laser unit; (103-1) First laser transmitter; (103-n) N^th laser transmitter; (105-1) First laser receiver; (105-n) N^th laser receiver; (107) Analyzer
