RADAR APPARATUS AND ANTENNA APPARATUS

摘要

PURPOSE: A radar device is provided to concentrates antenna benefits in the direction to be sensed. CONSTITUTION: A radar device (100) comprises a long distance transmitting antenna part (111), a short distance transmitting antenna part (112), a receiving antenna part (113) and a signal transmitting and receiving part (120). The long distance transmitting antenna part comprises multiple long distance transmitting array antennas. The short distance transmitting antenna part comprises one or more short distance transmitting array antennas. The receiving antenna part comprises multiple receiving array antennas. The signal transmitting and receiving part transmits a signal through one or more of the long distance transmitting antenna or the short distance antenna and receives the signal reflected from surroundings after being received through the receiving antenna.
