Automatic dependent surveillance-broadcast time delay estimation based on extended recursive maximum correntropy algorithm

Abstract

In this study, a novel adaptive algorithm, termed extended recursive maximum correntropy (EX-RMC), is proposed to estimate the time delay of automatic dependent surveillance-broadcast (ADS-B), an up-to-date surveillance technology in civil aviation. The proposed algorithm is designed to deal with both the random time-varying delay and the impulsive noise. The superiority of EX-RMC in tracking time-varying state of an unknown plant has been verified by simulation experiments. On-site experiments are also carried out to demonstrate the practical value of the ADS-B time delay estimation method based on EX-RMC.
