Abstract
The present invention provides a radar apparatus capable of changing a characteristic of filter processing while considering also a relative velocity of an object. A measurement section measures a relative position and a relative velocity of an object such as another vehicle, a pedestrian, and an object placed on a road. The radar apparatus calculates a time until the object and an own vehicle collide with each other, based on the relative position and relative velocity of the object measured by the measurement section, and changes, based on the calculated time, a filter coefficient to be used when filter processing is performed on a measured position converted from the measured relative position of the object, thereby changing a characteristic of the filter processing to be performed on the measured position, between stability and responsiveness.
