Claim 16:
17. A signal processing method for a radar device including a first module that generates a first transmission signal using a first local oscillation signal, transmits the first transmission signal, receives a reflection signal of the first transmission signal, and generates a first reception signal from the received reflection signal using the first local oscillation signal, a third module that generates a third transmission signal using a third local oscillation signal that is synchronized with the first local oscillation signal, and a signal processor that calculates an angle of a target, the method comprising:
receiving a reflection signal of the third transmission signal and generating a third reception signal using the first local oscillation signal, by the first module; and
detecting the target using the first reception signal and calculating the angle of the target using, for the target, a signal obtained by coherent integration based on the first reception signal and the third reception signal.
