Direction-of-arrival estimation (DOA) is an important and long-studied problem in array signal processing. Existing algorithms such as conventional delay-and-sum beamforming are limited in performance and become inadequate for a high-frequency broadband source and when the receiving linear array is sparse.

Dual-antenna GNSS spoofing detection method based on Doppler frequency difference of arrival
GPS Solutions, 2019Recent years have witnessed the emergence of portable global navigation satellite spoofing devices. A variety of anti-spoofing techniques have been dedicated to detecting the presence of spoofing signals, most of which solely utilize either signal characteristics or navigational information. However, since the GNSS system is under continuous monitoring

A novel Cramer-Rao lower bound of time difference of arrival for frequence hopping signals
2012 5th International Congress on Image and Signal Processing, 2012Frequency hopping signals have been widely used in military and civilian applications during the last few decades. It's of great value to locate emitters of frequency hopping signals, especially in military operations. Localization by time difference of arrival (TDOA) is a passive location method of good accuracy which utilizes the differences between ...

Frequency–wavenumber (f–k) analysis can determine the direction-of-arrival (DOA) for broadband signals captured by a vertical array [M. J. Hinich, J. Acoust. Soc. Am., 69, 732–737 (1981)]. The sparse vertical array generates numerous sidelobes in the f–k domain due to aliasing errors resulting from the spatial sampling. This presentation introduces the
