Beschreibung
Zusammenfassung:	[Object] To provide a remote airflow observation device, a remote airflow observation method, and a program that are capable of eliminating the influence of scattered waves from the ground or some object and improving the reliability of airflow observation.[Solving Means] A Doppler Lidar 100 includes: a measurement unit 110 that radiates transmission light including pulse-form laser light, receives reflected light of the radiated transmission light as reception light, and outputs a received signal for calculating a wind speed value on the basis of the transmission light and the reception light; and a signal processor 8 that performs processing for distributing the received signal to range bins by time-dividing the received signal and for removing a signal derived from a hard target from the received signal.
