Kind Code:
A1
Abstract:
A heater (9) is provided to a transmissive window (200) and heats the transmissive window. Reflective-wave-side substrates (25, 33) are arranged in a space on a side where reflected waves are detected, from among a space (103a) on a side where transmission waves are radiated and a space (103b) on a side where reflected waves are detected, the spaces being formed by dividing a transmissive-window-side space inside a housing (100) into two parts, and the substrates being arranged so that end parts thereof come into contact with the transmissive window. Temperature sensors (26, 32) detect the temperature of the heater. The temperature sensors also are installed on the transmissive-window side of the reflective-wave-side substrates.
