Decentralised and Centralised Fixed Structure H∞ Robust Loop Shaping for the MIMO Microsurgical Manipulation Based on PSOGSA

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper presents a robust H∞ decentralised and centralised control approach for a microsurgical manipulator using Particle Swarm Optimisation and Gravitational Search Algorithm (PSOGSA). The proposed fixed‐structure Proportional‐Integral‐Derivative (PID)‐based controllers address implementation challenges of conventional high‐order H∞ controllers ...

Optimal Designs of k‐Coincidence Wide‐Gap Frequency‐Hopping Sequence Sets

Electronics Letters, Volume 62, Issue 1, January/December 2026.
As a specific type of FHS, k$k$‐coincidence FHS sets enable their application in synchronous detection across numerous engineering fields due to their optimal self‐synchronization property. k‐coincidence uniform special FHS sets that possess wide‐gap and uniform properties contribute to enhancing the reliability and security of application systems ...

Radar Emitter Identification Based on Typical Parameter Sequence: HBNP Clustering, Hierarchical Denoising and LSTM Classification

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address “high‐density interference” and “multi‐mode parameter agility” in Radar Emitter Identification (REI), as well as existing models' flaws (pulse sequence models' weak anti‐noise ability, statistical feature models' multi‐mode confusion), this paper proposes a TPS‐based REI method–constructing a three‐level signal model and PRI probability ...

Optimal Sparse Array Design Against Desired Signal DOA Mismatch for Robust Adaptive Beamforming

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
The performance of the adaptive beamformer is not only related to the array weight but also influenced by the array structure. Different sparse array configurations exhibit varying sensitivities to uncertainties in the signal direction of arrival (DOA).

Off-Grid DOA Estimation Aiding Virtual Extension of Coprime Arrays Exploiting Fourth Order Difference Co-Array With Interpolation

IEEE Access, 2018
In this paper, a novel array structure exploiting coprime arrays is proposed which can be very proficient to determine the number of consecutive lags in proportion with the number of array elements.

A Direct Localization Method for Coprime Arrays Based on Averaging of Redundant Data of Virtual Array Elements

IET Signal Processing, Volume 2026, Issue 1, 2026.
To address the issue that the traditional direct position determination (DPD) method for coprime arrays (CAs) has limited performance in scenarios with low signal‐to‐noise ratio (SNR) and small quantity of observation data, a progressive optimization method based on the averaging of redundant data from virtual array elements is proposed. This method is

A Novel Noncircular MUSIC Algorithm Based on the Concept of the Difference and Sum Coarray

Sensors, 2018
In this paper, we propose a vectorized noncircular MUSIC (VNCM) algorithm based on the concept of the coarray, which can construct the difference and sum (diff–sum) coarray, for direction finding of the noncircular (NC) quasi-stationary sources ...

Triple extended coprime array for single‐snapshot DoA estimation

Electronics Letters
The direction‐of‐arrival (DoA) estimation methods based on coprime array (CA) largely rely on having a sufficient number of snapshots. However, under single‐snapshot conditions typical of vehicle‐mounted imaging radar, CA‐based DoA estimation often ...

Direction of Arrival Estimation Using Augmentation of Coprime Arrays

Information, 2018
Recently, direction of arrival (DOA) estimation premised on the sparse arrays interpolation approaches, such as co-prime arrays (CPA) and nested array, have attained extensive attention because of the effectiveness and capability of providing higher ...

COPRIME ARRAYS WITH ENHANCED DEGREES OF FREEDOM

Anadolu University Journal of Science and Technology-A Applied Sciences and Engineering, 2018
Coprime array geometries provide robust performance for direction-of-arrival estimation problem with more sources than sensor elements. In previous works it is shown that K source directions can be resolved using only 2M + N -1 sensor elements where K is less than or equal to MN.
