A Novel Direction-of-Arrival Estimation via Phase Retrieval with Unknown Sensor Gain-and-Phase Errors

open access: yesSensors, 2019
In signal array processing, high-resolution direction-of-arrival (DOA) estimation algorithms work well on the assumption that the system models are perfect. However, in practicality, there are imperfect system models in which sensor gain-and-phase errors

Evaluation of Genetics in the Association Between Cardiorespiratory Fitness and Health

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT We evaluated how much cardiorespiratory fitness (CRF)‐related genetics contribute to the risk of common noncommunicable diseases (NCDs) and mortality, and whether individuals with different levels of CRF and genetic predispositions differ in health characteristics.

Direction of arrival estimation algorithm: Direction lock loop [PDF]

open access: yes, 2002
- In this paper, a new direction of arrival (DOA) estimation algorithm, direction lock loop (DiLL), is proposed. It has a similar concept to the delay lock loop (DLL) that is used for synchronization.

New Directions In Sparse Sampling and Estimation For Underdetermined Systems [PDF]

open access: yes, 2013
A central objective in signal processing is to infer meaningful information from a set of measurements or data. While most signal models have an overdetermined structure (the number of unknowns less than the number of equations), traditionally very few ...

Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]

open access: yes, 2011
Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.

Selective Range Iterative Adaptive Approach for High-Resolution DOA Estimation

open access: yesIEEE Access, 2019
In this paper, the problem of direction-of-arrival (DOA) estimation for a uniform linear array with single-snapshot observations is addressed. Two non-parametric DOA estimators are developed, which can be applied in any azimuth range with one snapshot ...
