摘要:
Provided is a multi-function radar apparatus capable of measuring both a distance to a target object and a temperature of the target object with high accuracy. A transmission signal produced from a high-frequency signal generating unit (9) is amplified by a transmission signal amplifying unit (12) while intermittently stopped by a transmission intermittent stop switch (11), and is emitted to a target object (13) via a circulator unit (2). A reflected wave from the target object (13) is input as a reception signal to a transmitting and receiving antenna (1) while the transmission signal is emitted, and a radiated wave from the target object (13) is input as the reception signal thereto while the transmission signal is not emitted. The reception signal is amplified by a reception signal amplifying unit (3) via the circulator unit (2), and is mixed by a frequency converting unit (4) with the transmission signal branched by a high-frequency signal branching unit (10) to thereby generate a beat signal. A signal processing unit (6) calculates the distance to the target object (13) and the temperature of the target object (13) based on the beat signal amplified by a beat signal amplifying unit (5).
