Abstract
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 () is amplified by a transmission signal amplifying unit () while intermittently stopped by a transmission intermittent stop switch (), and is emitted to a target object () via a circulator unit (). A reflected wave from the target object () is input as a reception signal to a transmitting and receiving antenna () while the transmission signal is emitted, and a radiated wave from the target object () 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 () via the circulator unit (), and is mixed by a frequency converting unit () with the transmission signal branched by a high-frequency signal branching unit () to thereby generate a beat signal. A signal processing unit () calculates the distance to the target object () and the temperature of the target object () based on the beat signal amplified by a beat signal amplifying unit ().
