A detection area determining unit () determines a detection area where there is a possibility that a tsunami occurs. A current velocity estimating unit () estimates, as a sea-surface velocity of current in the detection area, a value obtained by smoothing sea-surface velocity of currents corresponding to cells included in the detection area. A tsunami detecting unit () detects occurrence of the tsunami in the detection area, based on the sea-surface velocity of current estimated by the current velocity estimating unit ().

Radar apparatus

An observation area is divided into coarse resolution areas each being an area larger than a range cell, a coarse-resolution-area creating unit () is provided to calculate a Doppler velocity for each coarse resolution area on the basis of Doppler velocities in a plurality of range cells included in each coarse resolution area among Doppler velocities in range cells calculated by a Doppler velocity calculating unit (), and a range cell detecting unit () detects a range cell in which an observation target is present from the Doppler velocity for each coarse resolution area calculated by the coarse-resolution-area creating unit () and the Doppler velocities for the range cells calculated by the Doppler velocity calculating unit ().
