Coherent FDA Receiver and Joint Range-Space-Time Processing
Wenkai Jia, Andreas Jakobsson, Wen-Qin Wang
When a target is masked by mainlobe clutter with the same Doppler frequency, it is difficult for conventional airborne radars to determine whether a target is present in a given ob…
Determining Joint Periodicities in Multi-time Data With Sampling Uncertainties
David Svedberg, Filip Elvander, Andreas Jakobsson
In this work, we introduce a novel approach for determining a joint sparse spectrum from several non-uniformly sampled data sets, where each data set is assumed to have its own, po…
Defining Fundamental Frequency for Almost Harmonic Signals
Filip Elvander, Andreas Jakobsson
In this work, we consider the modeling of signals that are almost, but not quite, harmonic, i.e., composed of sinusoids whose frequencies are close to being integer multiples of a…
Compressed Sensing for Reconstructing Coherent Multidimensional Spectra
Zhengjun Wang, Shiwen Lei, Khadga Jung Karki +2
We apply two sparse reconstruction techniques, the least absolute shrinkage and selection operator (LASSO) and the sparse exponential mode analysis (SEMA), to two-dimensional (2D)…
On Harmonic Approximations of Inharmonic Signals
Filip Elvander, Jie Ding, Andreas Jakobsson
In this work, we present the misspecified Gaussian Cramér-Rao lower bound for the parameters of a harmonic signal, or pitch, when signal measurements are collected from an almost,…
Mismatched Estimation of Polynomially Damped Signals
Filip Elvander, Johan Swärd, Andreas Jakobsson
In this work, we consider the problem of estimating the parameters of polynomially damped sinusoidal signals, commonly encountered in, for instance, spectroscopy. Generally, findin…
