Abstract
A radar device () includes a frequency conversion part () which converts a frequency of an echo signal obtained by reflecting a detection signal and receiving the reflected detection signal by an antenna (), and amplifies a signal level thereof. The radar device () includes a path switching part () which outputs, as a calibration signal, to the frequency conversion part (), the transmission signal output by the transmission signal generation part () at a timing while the transmission signal is output to the antenna (). A gain adjustment part () changes an amplification gain of the frequency conversion part () on the basis of a signal level of the calibration signal input to the frequency conversion part () and a signal level of the calibration signal having been amplified by the frequency conversion part ().
