Methods for subset selection can be used to address the modal retrieval problem using an
overcomplete dictionary composed of elementary damped sinusoids. Apart from the related …

This paper develops a procedure for the design of frequency-selective interpolation
operators that can be computed and saved once and for all. These operators are used to …

The problem considered is to match the periodogram (spectrum) of a real sampled data
sequence when only the samples outside a gap are available: that is, when the samples in …

The adaptive weighted norm extrapolation (AWNE) procedure of Cabrera and Parks (1991)
is generalized to non-uniform one-dimensional (1-D) and two-dimensional (2-D) sampling …

We consider the problem of exact support recovery of sparse signals via noisy
measurements. The main focus is the sufficient and necessary conditions on the number of …

基于自回归(auto-regressive, AR) 模型的参数化虚拟孔径合成算法无法应用于灵活的稀疏阵列
构型, 在单快拍和低信噪比(signal-to-noiseratio, SNR) 时对极点个数和位置估计不准 …

High‐frequency (HF) over‐the‐horizon radar (OTHR) works in a very complicated
electromagnetic environment. It usually suffers performance degradation caused by …

In this paper, we present an extrapolation approach, which uses minimum weighted norm
constraint and minimum variance spectrum estimation, for improving synthetic aperture …

Because of the ill-posed nature of equivalent source method (ESM)-based nearfield acoustic
holography (NAH), regularization methods based on the minimum L2-norm criterion such as …

Many time-frequency distribution (TFD) implementations involve block processing of
samples of the signal under analysis. The extraction of a finite amount of data and the …
