Nonparametric if and DOA estimation

Seventh International Symposium on Signal Processing and Its Applications, 2003. Proceedings., 2003
A nonparametric algorithm for estimation of instantaneous frequency (IF) and direction-of-arrival (DOA) of wideband FM signals, at the uniform linear array (ULA), is considered. The IF estimation of signals received at the sensor array is performed by using positions of the Wigner distribution (WD) maxima.

DOA Estimation in heteroscedastic noise

Signal Processing, 2019
The paper considers direction of arrival (DOA) estimation from long-term observations in a very noisy environment. The concern is to derive methods obtaining reasonable DOAs at very low SNR. The noise is assumed zero-mean Gaussian and its variance varies in time and space, causing stationary data models to fit poorly over long observation times ...

Kalman-based estimator for DOA estimations

IEEE Transactions on Signal Processing, 1994
We introduce a new Kalman-based noise-subspace estimator combined with the Root-MUSIC for direction of-arrival (DOA) estimation of uncorrelated narrow-band plane waves impinging on an array of sensors. Without both a priori knowledge of the number of sources and the inflation method presented by Yang and Kaveh (1988), we show that the Kalman-based ...

DOA estimation with hexagonal arrays

Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002
Hexagonal arrays are widely used in practice but have received less attention in the optimum array processing literature. In this paper, we show how unitary ESPRIT can be applied to hexagonal arrays for direction-of-arrival (DOA) estimation. The resulting estimates exhibit good threshold behavior, and are close to the Cramer-Rao bound above threshold ...
