Kind Code:

A1

Abstract:

[Problem] To provide an FMCW radar device, wherein it is possible to eliminate any effect based on local feed-through. [Solution] Provided is a radar device comprising: an oscillator for oscillating a local signal; a transmission antenna for emitting a transmission signal based on the local signal; a reception antenna for receiving a reflected wave reflected by a target of the transmission signal; a mixer for generating a multiplied signal by multiplying the reflected wave and the local signal together; and a first shifter provided between the oscillator and the mixer, the first shifter shifting the phase of the local signal.
