1. A communication device comprising:
- a transmitter for transmitting an ultra wide band wireless wave pulse;
a plurality of receivers which are disposed equidistant from the transmitter and receive the ultra wide band wireless wave pulse; and
distance-measuring equipment which detects a distance or a direction to an object based on reception times when each of the receivers receives the ultra wide band wireless wave pulse directly from the transmitter and an object-reflected wave thereof.

Abstract
A communication device is disclosed which is comprised of: a transmitter for transmitting an ultra wide band wireless wave pulse; multiple receivers which are disposed equidistant from the transmitter and receive the ultra wide band wireless wave pulse; and distance-measuring equipment which detects a distance or a direction to an object by measuring time intervals between the first reception times when receivers receive the ultra wide band wireless wave pulse directly from the transmitter and the second reception times when the receivers receive a object-reflected wave of the ultra wide band wireless wave pulse.

3. A communication system comprising:
-
a detector including a transmitter which transmits a response request using an ultra wide band wireless wave pulse;
a plurality of receivers which are disposed equidistant from the transmitter and receive the ultra wide band wireless wave pulse; and
distance-measuring equipment which detects a distance or a direction to an object based on reception times when each of the receivers receives the ultra wide band wireless wave pulse directly from the transmitter and an object-reflected wave thereof; anda response device including a receiver which is installed on the object and receives the ultra wide band wireless wave pulse transmitted from the transmitter of the detector; and
a transmitter which transmits a response request using another ultra wide band wireless wave pulse in response to the reception of the ultra wide band wireless wave pulse from the detector by the receiver of the response device.
