Beschreibung
Zusammenfassung:	A method and a system are described for localisation and tracking of moving vehicles using auxiliary array antennae, dual space-frequency estimators and interferers discriminators. Doppler effect is compensated by performing an estimate of the frequency drift rate. By stamping an absolute time reference for the digital signal samples, the frequency drift rate associated with Doppler effect is calculated and can be compensated. Then, the DoA is statistically calculated by computing the spatial correlation to locate the moving vehicle e.g. an aircraft or spacecraft, taking into account a previously generated parametric calibration model.
