1. A sensor fusion system for a vehicle, the sensor fusion system comprising:

  • a radar device configured to receive a signal wave reflected from a target object, and identify a type of the target object based on a measured reception power of the signal wave by using a preliminarily created database that stores, for a plurality of different object types, a relationship between a distance to a reference object and a reception power of a reference signal wave that is reflected from the reference object;

    a camera device configured to identify the type of the target object; and

    a sensor fusion section configured to determine whether the type of the target object identified by the radar device is equal to the type of the object identified by the camera device,wherein the radar device comprises a database update block that updates the database when the type of the object identified by the radar device is different from the type of the object identified by the camera device.
