摘要： Method for localizing a wireless node in a wireless sensor network, and wireless node using the method. The method includes sending a chirp spread spectrum signal with a carrier frequency from a first wireless node (A) to a second wireless node (B), the second wireless node (B) including a plurality of antennas; receiving the chirp spread spectrum signal at the plurality of antennas; executing time-of-arrival ranging between the first and second wireless nodes (A, B) for determining a distance between the first and second wireless nodes (A, B); and detecting a relative phase shift of the received chirp spread spectrum signal at each of the plurality of antennas of the second wireless node (B) and determining a direction of the first wireless sensor node (A) with respect to the second wireless sensor node (B) from the detected relative phase shift.
