Abstract
The present disclosure relates to a method and apparatus for detecting a target object by a radar device for a vehicle. The method includes recognizing the situation that causes the deterioration in the function of a radar, and preventing the performance from deterioration through a signal processing technology. The apparatus includes: a signal transmitting unit that transmits a transmission signal for detecting a target object; a signal receiving unit that receives a reception signal generated by a reflection of the transmission signal; a signal analyzing unit that calculates frequency spectrum information of the reception signal, and extracts periodicity information for determining a periodicity of the frequency spectrum information; a determining unit that determines whether a clutter structure exists; and a target detecting unit that detects a target object by deleting a peak value component of the periodicity information when it is determined that the clutter structure exists.
