1. A method for monitoring carrier phase anomalies in a range finding system comprising: predicting a relative carrier phase between first and second antenna locations as a function of a relative position between the two antenna locations; measuring a relative carrier phase between the first and second antenna locations based upon at least one transmitted signal received at each of the first and second antenna locations; calculating an anomaly detection metric as a function of a difference between the measured relative carrier phase and the predicted relative carrier phase; and determining if an anomaly is present according to the anomaly detection metric.
