Do you or others know how these are usually tracked?

Thanks Daniel,
My site only tracks aircraft that transmit ADS-B which is usually commercial aircraft. Non ADS-B transmitting aircraft either need multlateration (MLAT) which I believe is where aircraft locations are calculated mathimatically by multiple people receiving ModeS signals and sharing the data (I could be wrong here). Or alternatively by standard radar.
