CONSTITUTION: An AD converter(100) converts four or more RF signals received from multiple antennas into digital signals. A power measurement and channel selection unit(200) selects a channel having a biggest reception signal and the reception channel of left and right thereof after receiving a multi-channel digital signal from the AD converter and measuring the power of the signal of each channel. A high definition TOA measuring unit(300) measures the TOA of the biggest reception signal by using the high precision visual data of inside or outside in the signal of the biggest reception signal. A channelizer/phase detector(400) measures a signal frequency, a signal strength, a pulse width, and a signal phase. An AOA(Angle of Arrival) measuring unit(500) measures an AOA by using the signal strength of each channel and a phase at the same time. A PDW generating unit(600) generates a PDW as a pulse unit by assembling the measured result and outputs the PDW to an external link device by storing in a fixed time or number.
