ABSTRACT:
A radar apparatus includes a modulation signal generating unit that generates a modulation signal based on an internal clock with a cycle Tc and generates a trigger signal in synchronization with the modulation signal, a carrier wave generating unit that generates a carrier wave, a modulation unit that generates and outputs a high frequency signal by modulating the carrier wave using the modulation signal, a modulation signal extracting unit that extracts the modulation signal from a component of the high frequency signal that has been transmitted via a transmission antenna, the component having been reflected by a measured object and received by a reception antenna, a detection signal generating unit that generates a detection signal, for measuring a distance to the measured object, based on the trigger signal and the extracted modulation signal, and a pulse width calculating unit that calculates a pulse width of the detection signal.
