Elliptical DoA Estimation & Localization

IEEE Journal of Radio Frequency Identification, 2021
Summarization: This work puts forth elliptical direction of arrival (DoA) estimation and localization, using phase-based, narrowband measurements. The method exploits a multistatic architecture, where illuminating and receiving antennas are placed in the

Rational Arrays for DOA Estimation

ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022
Linear arrays used in array processing usually have sensor positions r_iλ/2 where λ is the wavelength of the impinging signals and r_i are integers. This paper considers rational arrays, where r_i are rational numbers. In particular, sparse rational arrays such as coprime rational arrays are introduced.

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 ...
