Direction of Arrival Estimation Accuracy Enhancement via Using Displacement Invariance Technique

International Journal of Antennas and Propagation, 2015
A new algorithm for improving Direction of Arrival Estimation (DOAE) accuracy has been carried out. Two contributions are introduced. First, Doppler frequency shift that resulted from the target movement is estimated using the displacement invariance ...

Unitary ESPRIT algorithm for bistatic MIMO radar

Electronics Letters, 2012
A new Unitary ESPRIT algorithm for joint direction of departure (DOD) and direction of arrival (DOA) estimation in bistatic MIMO radar is proposed. The properties of centro-Hermitian matrices are utilised to transform the complex-valued data matrix into a real-valued data matrix.

FDA‐MIMO Range and Angle Estimation Based on Hybrid Tensor Ring and CP Decomposition

Electronics Letters, Volume 62, Issue 1, January/December 2026.
The graphical abstract illustrates the RMSE performance of range and angle estimation versus SNR for different array configurations. The proposed method consistently achieves lower estimation error than existing approaches and closely matches the Cramér‐Rao bound across the entire SNR range, demonstrating its superior accuracy.

Shaped extensions of singular spectrum analysis [PDF]

, 2014
Extensions of singular spectrum analysis (SSA) for processing of non-rectangular images and time series with gaps are considered. A circular version is suggested, which allows application of the method to the data given on a circle or on a cylinder, e.g.

Monitoring Bridge Vibrations via Spaceborne SAR Micro‐Doppler

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
The advent of Synthetic Aperture Radar (SAR) imaging has presented the possibility of remote monitoring of civil infrastructure on a large scale. Although well established for observing slow and long‐term phenomena, its application to vibration‐based structural health monitoring (SHM) remains relatively unexplored in the current literature.

Source localization for underwater acoustics using esprit algorithm

IOP Conference Series: Materials Science and Engineering, 2021
Abstract In order to perform the underwater source localization, vector sensors play a major role. If vector sensors are used as an array, the gain can be improved and the accuracy can also be improved. In furtherance of finding the direction of arrival (DOA) of the sound signal which is nothing but the source localization, there are ...

Trigonal Bipyramidal Clusters [Tl5]7−: Synthesis and Characterization of the Zintl Phase K7−xAxTl5 (A = Rb, Cs; 0 < x ≤ 2.35)

Chemistry – A European Journal, Volume 31, Issue 70, December 12, 2025.
Mixed alkali metals, potassium and additional rubidium or cesium, allow for the synthesis of a straightforward, electron‐precise Zintl phase K7−xAxTl5. The new phase is characterized by SCXRD, PXRD, and DFT. Its metastability is proven by DSC measurements.

Perspectives on the Current and Future State of Artificial Intelligence in Medical Genetics

American Journal of Medical Genetics Part A, Volume 197, Issue 10, October 2025.
ABSTRACT Artificial intelligence (AI) is rapidly transforming numerous aspects of daily life, including clinical practice and biomedical research. In light of this rapid transformation, and in the context of medical genetics, we assembled a group of leaders in the field to respond to the question about how AI is affecting, and especially how AI will ...

Direction-of-Arrival Estimation with Coarray ESPRIT for Coprime Array

Sensors, 2017
A coprime array is capable of achieving more degrees-of-freedom for direction-of-arrival (DOA) estimation than a uniform linear array when utilizing the same number of sensors.
