To keep the performances of a radar system and a sensor interface system high and stable even when a relative distance to a target increases or decreases extensively and rapidly, without complicating their system structures drastically, in the radar system mounted on the same moving body together with a velocity sensor or an acceleration sensor, and the sensor interface system for interfacing between the radar system and any one of these sensors.
This radar system identifies any one of the velocity, a distance, the position, and a property of the target on the basis of an arrival wave having arrived from the target in response to a wave signal, and has: and a Doppler shift specifying means for specifying the velocity of the moving body or the radar system in the direction of transmission of the wave signal by using the velocity sensor or the acceleration sensor mounted on the same moving body together with the radar system, and also specifying a Doppler shift produced in the wave signal in accordance with the velocity. The radar system has a correction means for correcting the frequency of the wave signal over the Doppler shift.
