APPARATUS AND METHOD FOR PREDICTING A VIRTUAL DISTANCE USING A NON-STREAMING AVERAGE DELAY SPREAD IN A TIME INVARIANT CHANNEL AND ESTIMATING A RADIAL DIRECTION BASED ON THE ANTENNA

摘要

Disclosed is an apparatus and method for estimating a location of a source for estimating a virtual distance using an uncorrelated mean delay spread in a time invariant channel and estimating a radiation direction based on an antenna. The method of estimating a location of a source includes driving an omni antenna; When the omni antenna receives a signal transmitted from a source, moving a position of the omni antenna according to a preset observation range and a position control interval; Determining whether a channel is a stable channel or a fading channel using a channel impulse response characteristic of a signal received at the position of the moved omni antenna; Predicting a virtual distance from a location where a signal determined as a stable channel is received to a source; Adjusting a vertical angle and a rotation angle of the horn antenna combined with the omni antenna according to the predicted false distance; Driving the horn antenna at a position where a signal determined as a stable channel is received; And predicting a virtual radiation angle from the horn antenna to the source according to the angle of the received signal by the driven horn antenna.
