METHOD FOR ESTIMATING THREE DEMENSIONAL MULTI-BASELINE ANGLE OF ARRIVAL, AND DEVICE USING THE SAME

摘要

PURPOSE: A method and device for estimating 3D multi-baseline direction is provided to reduce an amount of memories for storing data by making lookup table data through an Euler angular transformation. CONSTITUTION: Three or more receivers(110) receive a wireless signal from a wireless signal source. A phase detector(120) receives a wireless signal from two receivers. A phase difference between wireless signals is outputted. A calculating unit(430) receives the phase difference and calculates AOA(Angle of Arrival) by referring to a direction detecting lookup table. A direction detecting lookup table(440) stores data using an Euler angular transformation.
