Abstract

The multipath interference affects the navigational accuracy of the Microwave Landing System (MLS), which threatens the landing security of planes seriously. The common methods of the multipath interference suppression are realized on the electromagnetic modeling of the airport environment, which have huge computation and complicated design, etc. A novel method based on the power-cepstrum technology is proposed to restrain the multipath signal of MLS. Firstly, the mathematical model of the signals received by the navigational equipments on the plane. And then, the power-cepstrums of the signals are calculated and the multipath effect is counterbalanced so that the time delay between the toward-and-back scanning beams is estimated precisely. Finally, its effectiveness is proved by the simulation and experiment.
