Abstract
A radar device calculates positions and relative velocities of points of reflection from an FMCW beat signal, extracts stationary reflection points each being a point of reflection having a relative velocity of zero, and sets, for each of the stationary reflection points, an object area estimated to contain an object including the stationary reflection point. The radar device calculates positions and relative velocities of points of reflection from a 2CW beat signal from which a DC component has been removed, extracts in-area reflection points each being a point of reflection that belongs to the object area. The radar device then computes, for each of the in-area reflection points, a cross velocity that is a velocity of the in-area reflection point in a cross-range direction, and statistically processes calculated cross velocities for each of the object areas. The radar device calculates an estimated value of a cross velocity of an object.
