ABSTRACT:
Techniques, systems and computer readable medium are disclosed for measuring a position of an object device. A position measuring apparatus includes a receiving unit designed to receive a signal transmitted from an object device for position measurement. The position measuring apparatus also includes a position computing unit designed to compute a position of the object device by applying Angle Of Arrival (AOA) and Time Of Arrival (TOA) techniques using the received signal. The position measuring apparatus also includes a medium channel estimating unit designed to estimate a channel of a medium, through which the received signal penetrates on a transmission path, using the received signal. The position measuring apparatus also includes a position correcting unit configured to compute a delay time caused by the received signal penetrating the medium using the estimated medium channel and correcting the position of the object device computed by the position computing unit using the delay time.
