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 toCk target angle estimates calculated by the target angle estimator.

Vehicle radar device and control method

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.
