Application of Advanced Signal Processing Techniques to Angle of Arrival Estimation in ATC Navigation and Surveillance Systems

Abstract

This report focuses on the mitigation of multipath and/or incoherent (cochannel) interference on receiving antenna arrays since these phenomenon represent a principal challenge to many existing ATC systems. The improved signal processing techniques considered explicitly assume that interfering signals may be present and estimate the interference parameters (e.g., power and angle of arrival) as well as the desired signal parameters. By thus identifying the nature of the interference, it is then possible to reduce its effects on the desired signal angle of arrival estimates.
