Research Progress on Coprime Array Signal Processing: Direction-of-Arrival Estimation and Adaptive Beamforming

Leida xuebao, 2019
Array signal processing is an essential tool in broad radar applications. The coprime array has recently been proposed to overcome the bottleneck caused by the Nyquist spatial sampling rate.

A fast data-driven method for inverse microphone array signal processing [PDF]

JASA Express Letters, 2023
Microphone arrays have long been used to characterize and locate sound sources. However, existing algorithms for processing the signals are computationally expensive and, consequently, different methods need to be explored.

Design of mine-used intrinsically safe line array X-ray receiving box

Gong-kuang zidonghua, 2021
The mine-used explosion-proof line array X-ray receiving box is not suitable for nondestructive testing of high-speed conveyor belts. And there are difficulties in processing the explosion-proof enclosure and heavy weight for nondestructive detection of ...

Source enumeration via RMT estimator with adaptive decision criterion based on linear shrinkage estimation of noise eigenvalues using relatively few samples

IET Signal Processing, 2022
Estimating the number of signals embedded in noise is a fundamental problem in array signal processing. The classic random matrix theory (RMT) estimator based on RMT does not consider the bias term of the expectation of the eigenvalue being tested, and ...
