Abstract
A radar device capable of removing noise signals before digital conversion and detecting an object with high precision by a simple configuration is provided. In a transmitting RF unit, a signal switchis switched so that the noise signal generated by the operation of a first switchpasses through a signal delaying device. The signal switchis switched so that the noise signal generated by the operation of a second switchpasses through a signal delaying device. Furthermore, the signal switchis switched so that a baseband pulse signal obtained when the first switchand the second switchare operated at the same time passes through a signal delaying device. In a signal synthesizer, synthesizing is carried out so that the noise signals mixed in pulse signals are cancelled out.
