System and method for continuous carrier wave reconstruction

摘要

A system and method of continuous carrier wave reconstruction includes a radio navigation receiver that includes one or more processors, memory coupled to the one or more processors, and an input for receiving a signal from a transmitter. The signal has a phase. The one or more processors are configured to obtain phase lock on the received signal, extract first phase information from the received signal, detect a loss in phase lock on the received signal, and extrapolate second phase information while phase lock is lost using a model of the phase. In some embodiments, the one or more processors are further configured to reconstruct the carrier signal based on the first and second phase information. In some embodiments, the one or more processors are further configured to scale the first and second phase information from a first nominal frequency of the received signal to a different second nominal frequency.

1. A system comprising:
one or more processors; memory coupled to the one or more processors; and a radio navigation receiver for receiving a signal from a transmitter, the signal having a phase; wherein the one or more processors are configured to perform operations comprising:
obtaining a phase lock on the received signal;extracting first phase information from the received signal;detecting a loss in phase lock on the received signal; andextrapolating second phase information while phase lock is lost using a model of the phase, the extrapolating comprising:
determining a relative velocity between the radio navigation receiver and the transmitter; anddetermining the second phase information based at least in part on the relative velocity.
