摘要： A receiving unit is disclosed, including at least three receivers, each configured to receive an ultrasonic signal with a wavelength λ from the transmitting unit. A first receiver is arranged at a distance of at most one half wavelength λ/2 of the ultrasonic signal from a second receiver and from a third receiver. The at least three receivers are arranged in one plane. A processor is configured to determine the respective time-of-flight from the ultrasonic signal received at each of the at least three receivers. The respective time-of-flight is a time that the ultrasonic signal requires from the transmitting unit at a defined start time to the respective receiver. The processor is further configured to determine the three-dimensional position and/or direction of the transmitting unit from the determined times-of-flight and the arrangement of the at least three receivers.
