Abstract
A passive locator and method for a wireless communication system. The locator (56) at base station (12) determines the position and trajectory of wireless terminal (22). The passive locator (56) adjusts azimuthal and elevational angles of a directional antenna (58) until a relative maximum power is detected in the signal transmitted from the wireless terminal (22). A processing circuit (60) determines the trajectory of the wireless terminal (22) by generating and analyzing data that represents the Doppler effect on the signal from the wireless terminal (22).
