HYDROGRAPHIC PHENOMENON DETECTION DEVICE, RADAR DEVICE, HYDROGRAPHIC PHENOMENON DETECTION METHOD, AND PROGRAM

摘要

[Problem] To provide a hydrographic phenomenon detection device, radar device, hydrographic phenomenon detection method, and program with which accurate information about a hydrographic phenomenon in the periphery of a boat or the like can be more readily detected. [Solution] A hydrographic phenomenon detection device (3) has a Doppler speed map generation unit (12) and a hydrographic phenomenon data generation unit (13). On the basis of a received signal (S2) comprising amplitude information and phase information, the Doppler speed map generation unit (12) generates Doppler speed map data (D3) for identifying the distribution of Doppler speed vectors (DV53, DV54) for hydrographic phenomena (a wave (53) and a surface tide (54)). On the basis of the Doppler speed map data (D3), the hydrographic phenomenon data generation unit (13) generates hydrographic phenomenon data (wave data (D4) and surface tide data (D5)) for identifying the hydrographic phenomena.
