Abstract:
The apparatus includes a transmission signal divider for dividing and transmitting a received signal to a transmission antenna and an attenuator, an attenuator for applying a predetermined attenuation factor to the transmitted signal divided to the attenuator, a phase shifter for phase-shifting the signal to which the attenuation factor is applied by a predetermined phase, and a time delayer for time-delaying the phase-shifted signal by a predetermined time.
