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

A microwave irradiating and heating device including: a reaction furnace containing a sample material to be irradiated with a microwave passed through an opening and to be heated; a microwave irradiating source disposed outside the reaction furnace; a rotated quadric surface mirror reflecting microwave emitted from the microwave irradiating source toward the opening, and disposed above the reaction furnace; a lid for the opening, at least a portion of the lid made from dielectric to transmit microwave reflected on the rotated quadric surface mirror into the reaction furnace; wherein an angle of incidence of the microwave, reflected on the rotated quadric surface mirror and irradiated at the portion of the lid made from the dielectric, is at an angle causing a polarized wave of the microwave to pass through the portion.
