Abstract:A novel algorithm is proposed to locate the civil aviation ground interference source accurately and effectively via plane scattered signals. Firstly, a new method of arranging initial reference points is raised which is analyzed theoretically and testified experimentally. Secondly, correntropy and weighted centroid are introduced to optimize the existing locating algorithm. Both analyses and experiments are carried out. Simulation results show that the proposed algorithm improves the locating accuracy significantly and it has better practicality under equal amount of computations.
Keywords:interference source locating   civil aviation   Doppler frequency shift   correntropy   weighted centroid
