Empirical model of the ADS-B channel for airport area

The paper describes approach to processing of the ADS-B extended squitter signals and data provided by targets on the ground area of the airport. These signals are affected by radio channel environment which causes distortion and interference. The paper presents a method for estimation of the channel TDL model based on empirical data processing. This method is applied on measurement and processing campaign with the real signals from MLAT transmitters at the Prague Vaclav Havel airport. The results of channel model parameters are presented here as well.
