Abstract: One embodiment of the disclosure relates to a vehicle radar device and a method for controlling the same. According to the present embodiments, a vehicle radar device may comprise an antenna unit including Nt transmission antennas and Nr reception antennas, wherein Nt is a natural number equal to or larger than 1, and Nr is a natural number equal to or larger than 2, a transceiver controlling the transmission antenna to transmit a transmission signal and the reception antenna to receive a reception signal reflected by a target, a signal processor detecting one or more peak signals for the target and separately detecting Nt*Nr channel reception signals corresponding to each peak signal, a target angle estimator calculating a target angle estimate from k channel reception signals selected from among the Nt*Nr channel reception signals, and a target size information estimator calculating size information about the target based on up to NV*NrCk target angle estimates calculated by the target angle estimator.

Abstract: Disclosed is an apparatus for tracking an object based on radar image reconstruction, the apparatus including a two-dimensional image producing unit configured to produce a two-dimensional image by collecting multiple one-dimensional radar signals from which clutter is removed, an object detecting unit configured to determine the presence or absence of an object from the two-dimensional image and estimate a two-dimensional position of the present object, and an object tracking unit configured to track a movement path of the object based on the two-dimensional position estimated by the object detecting unit.
