Compressive frequency-difference direction-of-arrival estimation
Journal of the Acoustical Society of America, 2023Direction-of-arrival estimation is difficult for signals spatially undersampled by more than half the wavelength. Frequency-difference beamforming [Abadi, Song, and Dowling (2012). J. Acoust. Soc. Am. 132, 3018–3029] offers an alternative approach to avoid such spatial aliasing by using multifrequency signals and processing them at a lower frequency ...

IET Radar, Sonar and Navigation, 2015 This study presents a two‐step least‐squares approach for estimating the position and velocity of a moving emitter using time difference of arrival (TDOA) and frequency‐difference of arrival (FDOA) measurements in a two‐dimensional scenario. The proposed method first estimates the emitter position based on the asymptotes of TDOA hyperbolae and then ...

The problem of jointly estimating time difference of arrival (TDOA) and frequency difference of arrival (FDOA) or Doppler has a variety of practical applications. The conventional cyclic ambiguity function and the fractional lower-order ambiguity function suffer performance degradation in the presence of non-Gaussian α-stable impulsive noise and ...

Distributed time and frequency difference of arrival tracking in clutter
2012 Workshop on Sensor Data Fusion: Trends, Solutions, Applications (SDF), 2012We consider passive surveillance using time and frequency difference of arrival signals received by mobile receiver pairs. Signals received by a pair of receivers are correlated in time and frequency, followed by a detection process. In addition to the target (emitter) measurements, we may also create a number of spurious detections in each scan.

Combination of emitter localization techniques with angle, frequency and time difference of arrival
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013In this paper, finding the location of a stationary target with a moving platform is analyzed. The estimated measurements (direction, frequency, time difference of arrival) found by parameter estimation algorithms are used to find the target location. Different methods are combined and the improvement in location estimation is observed by using error ...
