VOR radio bacons are a type of short-range radio navigation system for aircrafts, distributed evenly to cover most of the airspace.
Coordinates and frequencies of all existing VOR beacons can be found at webside ourairports - check the navaids in map parameters.
VOR beacons work at carrier frequencies in range 108 - 118 HMz. Sampling of this 10 MHz wide band should make it possible to process all beacons at the same time. ADS-B data could be used to filter out know airplanes from the signal. Rest of the objects should be pick out as suspicious and should be further identified for example using a FDOA method.
Using VOR beacons to observe meteors has one advantage - these beacons work in a protected air band that is continuously monitored for interference. Therefore, the quality of obtained data is better than in other bands.
To process and digitise signals, a new digitizing unit should be available. It would be advantageous to change an SDRX01B receiver for a newer version, dedicated to digitise signal in bandwidth approximately 10 MHz, in order to improve the parameters of the receiving chain.
To obtain reference data and to filter airplanes, ADS-B data can be used.
