RECEIVING STATION AND METHODS FOR DETERMINING AN ANGLE-OF-ARRIVAL OF SHORT-DURATION SIGNALS USING SURFACE-ACOUSTIC-WAVE (SAW) DEVICES |
摘要 |
Embodiments of a system and method for determining an angle-of-arrival (AOA) of signals received from a transmitting device are shown. Signals from the transmitting device are received through two or more pairs of spatially-diverse antennas. A non-inverted version of the signals received through a first antenna of a pair is injected into a first input of a surface-acoustic-wave (SAW) device. An inverted version of the signals received through a second antenna of the pair is injected into a second input of the SAW device. Signals present at tap outputs are processed to determine a time-difference-of-arrival (TDOA) between the signals received through each pair of antennas. The AOA may be calculated from the TDOAs determined from two or more pairs of antennas.
