Abstract
An apparatus for estimating a Direction of Arrival (DOA) of a wideband includes a first signal receiving unit and a second signal receiving unit to receive a wideband signal while satisfying d≦Mc/2f, wherein 'd' denotes a distance the first signal receiving unit and the second signal receiving unit are spaced apart from each other, 'c' denotes the speed of sound, ‘M’ denotes a number of wideband frequencies being a number of fast Fourier transformation (FFT) points of a wideband signal, and ‘f’ denotes a sampling frequency, and a DOA calculating unit to calculate a DOA (θ) using a normalized frequency () which is obtained by performing an FFT on the respective wideband signals transmitted from the first signal receiving unit and the second signal receiving unit, and using the distance d.
