A method and apparatus for tracking and position determination includes generating carrier waves in transmitters; radiating said carrier waves; receiving said radiated carrier waves; imparting or simulating a motion, or motions, to radiators, reflectors or/and receiving antennas, within the locality of each, in such a way as to induce direction-dependent frequency modulation in each signal delivered to the receiving detectors; detecting said modulation on each received signal; and using measured parameters of said detected modulation to track the location of one or more of the said transmitters, reflectors or/and receivers and determine the corresponding position coordinates thereof. The actual or simulated motion of the radiators reflectors or antennas may have a uniform velocity along at least two straight, non-parallel lines.
