Fig. 7 shows some of the results for the estimated location
errors of the transmitter obtained by calculating the geometrical
position of the transmitter using the three averaged AOA
estimation results of the beamformer method. As you can see
from the results, it was confirmed that the average estimation
error was roughly within 10 m, except at P60, P400 and P700.
This was attributed to the fact that P400 and P700 were not
within line of sight and that there were some objects around
P60, thereby causing multipath signals
