摘要： An iterative process for computing the trajectory of one object containing a transmitter relative to another object containing a plurality of receivers is disclosed. The process contains a subprocess which estimates the trajectory band from the Doppler shifts in the signals measured by the receivers. The process contains another subprocess where the received Doppler signals are filtered by filter adapted to select the Doppler signals which would have been produced by an object following the trajectory estimated by the first subprocess.
