We consider the role played by the sensor locations in the optimal performance of an array of acoustic vector sensors. First we derive an expression for the Craá¸¿erâ€“Rao bound on the azimuth andâ€¦ (More)

Most array-processing methods require knowledge of the correlation structure of the noise. While such information may sometimes be obtained from measurements made when no sources are present, thisâ€¦ (More)

This paper establishes the large-sample accuracy properties of two nonlinear least-squares estimators (NLSE) of sine waves parameters: the basic NLSE, which ignores the possible correlation of theâ€¦ (More)

Coupling between two collocated orthogonal circular thin-wire loops is analyzed in this paper. Two coupled integral equations for the loop currents are derived and their solution in general form isâ€¦ (More)

The Ormia ochracea is able to locate a cricket's mating call despite the small distance between its ears compared with the wavelength. This phenomenon has been explained by the mechanical couplingâ€¦ (More)

We propose to design a small-size transmission-coupled antenna array, and corresponding radiation pattern, having high performance inspired by the female Ormia ochracea's coupled ears. Forâ€¦ (More)

A self-contained statistical analysis of the Pisarenko method for estimating sinusoidal frequencies from signal measurements corrupted by white noise is presented. An explicit formula is provided forâ€¦ (More)

An antenna consisting of three collocated orthogonal doubly loaded thin wire loops is discussed. This antenna is capable of simultaneously sensing vectors of electric and magnetic fields. Theâ€¦ (More)

This paper analyzes the performance of methods for estimating the parameters of narrowband signals arriving at an array of sensors. The so-called deterministic and stochastic maximum likelihood (ML)â€¦ (More)

Time difference of arrivals (TDOAs) of emitter wavefronts to spatially distributed array of sensors can be used to determine the source location. In this paper, we suggest a new method of TDOAâ€¦ (More)
