PROBLEM TO BE SOLVED: To provide a missile seeker device to detect wind generated by a helicopter hiding out in a recess of a mountain by a coherent Doppler LIDAR system and generate an induction signal induced thereto. SOLUTION: A missile seeker device comprises laser irradiation parts 16, 11, 12, and 13 to perform irradiation with laser, laser receiving parts 13, 12, 15, and 17 to receive a reflection wave by pointing to the same direction as that of an optical axis of irradiation and output an output signal based on the reflection wave, a detector 17 to detect the presence of an object based on a detected Doppler frequency by varying a frequency band by discriminating the frequencies of output signals from the laser receiving parts, and a LIDAR signal processing part 18 to output an induction signal related to the flying direction of a missile based on the detecting result. A turbulent flow of the atmosphere by a helicopter is detected by a coherent Doppler LIDAR system to induce a flying object.
