Joint Sparsity-Based Range-Angle-Dependent Beampattern Synthesis for Frequency Diverse Array
IEEE Access, 2017 For frequency diverse array (FDA) range-angle-dependent beampattern synthesis, the objective is to obtain the desired beampattern performance using fewer antenna elements or smaller aperture.

New Results on Boas–Bellman-Type Inequalities in Semi-Hilbert Spaces with Applications
Axioms, 2023 In this article, we investigate new findings on Boas–Bellman-type inequalities in semi-Hilbert spaces. These spaces are generated by semi-inner products induced by positive and positive semidefinite operators.

Moment of a subspace and joint numerical range
Linear and Multilinear Algebra, 2022 For a given complex finite dimensional subspace $S$ of $\mathbb{C}^n$ and a fixed basis, we study the compact and convex subset of $\left(\mathbb{R}_{\geq 0}\right)^n$ that we call the moment of $S$ $m_S=$ convex hull ($\{|s|^2\in\mathbb{R}^n_{\geq 0}: s\in S \wedge \|s\|=1\} )$ $\simeq \{ Diag(Y) \in M_n^h(\mathbb{C}):Y\geq 0, tr(Y)=1, P_S Y P_S=Y ...

Joint numerical ranges and compressions of powers of operators [PDF]
Journal of the London Mathematical Society, 2017 We identify subsets of the joint numerical range of an operator tuple in terms of its joint spectrum. This result helps us to transfer weak convergence of operator orbits into certain approximation and interpolation properties for powers in the uniform operator topology.

Target Association of Heterogeneous Sensors Based on Nearest-neighbor and Topology
Leida xuebao, 2012 A new data association algorithm is proposed in this paper for heterogeneous sensors information fusion system, which consists of Radar and high-dynamic-range IR, based on joint usage of the nearest-neighbor (NN) and the topology similarity. The proposed

Strict convexity of the joint c-numerical range
Linear Algebra and its Applications, 2013 Let \(H_{n}\) be the real vector space of \(n\times n\) complex Hermitian matrices. For any \(c=(c_{1},c_{2},\dots,c_{n})\in \mathbb R^{n}\) and an ordered \(m\)-tuple \(H=(H_{1},H_{2},\dots,H_{m})\in H_{n}^{m}\), the joint \(c\)-numerical range \(W_{c}(H)\) of \(H\) is defined.

A Note on the Joint Numerical Range of a Triple of 4-by-4 Hermitian Matrices
MathematicsWe present the degrees 14, 26 and 30 of the boundary generating surfaces of the joint numerical ranges for triples of 4-by-4 Hermitian matrices. This result completes the missing degrees from a previous study.
