Abstract
There is provided a radar receiver that effectively prevents local oscillator signals from leaking out from an antenna. A receiverincludes a local oscillator, a mixer, a buffer amplifier, and a mode switcher. The local oscillatoroutputs a local oscillation signal LO. The mixermixes a high-frequency signal RF received by a radar antennawith the local oscillation signal LO. The buffer amplifieris disposed between the local oscillatorand the mixer. The mode switcherswitches at least between a standby mode in which power is supplied to the local oscillatorand no power is supplied to the buffer amplifierand a reception mode in which power is supplied to both the local oscillatorand the buffer amplifier
