摘要: Provided is a pulse radar device which can attenuate an interference signal and significantly amplify a reflected wave without saturating the interference signal. A baseband amplifier unit (5) is installed in a pulse radar device (1) which is configured to transmit from antenna (3) a transmission pulse wave obtained by modulating a transmission control signal, and to be afterwards switched to a standby mode for a reflected wave obtained by reflecting the transmission pulse wave by an object to be detected. The baseband amplifier unit (5) includes: a first inverting amplifier (52) which amplifies the reflected wave; a first switch circuit (51) which is switched to a cut off state before the transmission control signal rises and is switched back to a conductive state when the transmission control signal falls, to thereby pass through a reflected wave which is input to the first inverting amplifier (52); and a second switch circuit (53) which is switched to the cut off state before the first switch circuit (51) becomes the cut off state and is switched back to the conductive state when the transmission control signal falls, to thereby pass through a signal which is output from the first inverting amplifier (52).
