“…Other migration methods back-propagate waves using various approximations, as in the oneway wave equation migration method (Claerbout 1985, Bleistein et al 2001. Narrowband methods use differential phase information of the full array response matrix and they image by beam-forming (Curlander andMcDonough 1991, Haykin et al 1993), or by fixed frequency subspace methods like multiple signal classification (MUSIC) (Schmidt 1979, 1986, Stoica and Moses 1997. Least-squares (maximum likelihood) direction-of-arrival (DOA) estimation methods (Haykin et al 1993) also use the full array response matrix in the frequency domain.…”

“…Therefore projecting into the null space of P(ω) at any fixed frequency will give a very good estimate of the target locations because they are exact zeros of the norm of the projection as a function of the search point y s (see (3.10)). This is, in fact, the well known MUSIC algorithm whose advantages over beam-forming and other target location methods is well known (Schmidt 1979, 1986, Stoica and Moses 1997.…”

Imaging and time reversal in random media

We present a general method for estimating the location of small, well-separated scatterers in a randomly inhomogeneous environment using an active sensor array. The main features of this method are (i) an arrival time analysis of the echo received from the scatterers, (ii) a singular value decomposition of the array response matrix in the frequency domain, and (iii) the construction of an objective function in the time domain that is statistically stable and peaks on the scatterers. By statistically stable we mean here that the objective function is self-averaging over individual realizations of the medium. This is a new approach to array imaging that is motivated by time reversal in random media, analyzed in detail previously. It combines features from seismic imaging like arrival time analysis with frequency-domain signal subspace methodology like MUltiple SIgnal Classification (MUSIC). We illustrate the theory with numerical simulations for ultrasound.

The low-temperature AC conductance of a one-dimensional electron system with a strong interaction of finite range is calculated by using linear response theory. The conductance factorizes into parts which depend on the internal properties of the system, and the external probe. For short-range interaction, the result resembles that for non-interacting electrons, but with the zero-frequency limit and the Fermi velocity renormalized by the interaction strength. For strong and long-range interaction, the conductance shows a peak that is related to chargewave excitations. In this limit, the AC conductance can be simulated by a quantum capacitance and a quantum inductance.

A generalized Prony method for reconstruction of sparse sums of eigenfunctions of linear operators

2013

View full text Add to dashboard Cite

We derive a new generalization of Prony's method to reconstruct M-sparse expansions of (generalized) eigenfunctions of linear operators from only O(M) suitable values in a deterministic way. The proposed method covers the wellknown reconstruction methods for M-sparse sums of exponentials as well as for the interpolation of M-sparse polynomials by using special linear operators in C(R). Further, we can derive new reconstruction formulas for M-sparse expansions of orthogonal polynomials using the Sturm-Liouville operator. The method is also applied to the recovery of M-sparse vectors in finite-dimensional vector spaces.
