Claim 9:
10. A method for object detection, the method comprising:
converting a part of a transmission signal received from a transmitter and a received signal acquired through a reflection of another part of the transmission signal from an object, into a digital transmission signal and a digital received signal, respectively, according to a predetermined sampling period;
interpolating between elements of the digital transmission signal and the digital received signal that have the predetermined sampling period, to obtain an interpolated transmission signal and an interpolated received signal;
removing noise from each of the interpolated transmission signal and the interpolated received signal;
generating a cross-correlation signal between the interpolated transmission signal from which the noise is removed and the interpolated received signal from which the noise is removed; and
acquiring a three-dimensional (3D) image of the object based on at least one peak value of the cross-correlation signal.
