A direct imaging method using far-field data
نویسندگان
چکیده
We present a direct imaging algorithm for extended targets using far field data generated by incident plane waves. The algorithm uses a factorization of the response matrix for far field data that derives from physical considerations, moreover, a resolution based regularization. The algorithm is simple and efficient since no forward solver or iteration is needed. Efficiency and robustness of the algorithm with respect to measurement noise are demonstrated.

A Direct Sampling Method for Inverse Scattering Using Far-field Data
This work is concerned with a direct sampling method (DSM) for inverse acoustic scattering problems using far-field data. Using one or few incident waves, the DSM provides quite reasonable profiles of scatterers in timeharmonic inverse acoustic scattering without a priori knowledge of either the physical properties or the number of disconnected components of the scatterer. We shall first presen...
متن کاملEffects of Far- and Near-Field Multiple Earthquakes on the RC SDOF Fragility Curves Using Different First Shock Scaling Methods
Typically, to study the effects of consecutive earthquakes, it is necessary to consider definite intensity levels of the first shock. Methods commonly used to define intensity involve scaling the first shock to a specified maximum interstorey drift. In this study the structure’s predefined elastic spectral acceleration caused by the first shock is also considered for scaling. This study aims to...
متن کاملRadial Field Retrieval in Spherical Scanning for Current Reconstruction and NF–FF Transformation
In this paper, a near-field to far-field (NF–FF) transformation for the case of spherical scanning using equivalent magnetic currents (EMCs) and matrix methods is addressed. It is based on the decoupling of the field components and the iterative retrieval of the radial component of the electric field. The technique is applied for far-field calculation as well as for the estimation of the curren...
متن کاملAn improvement in RTM method to image steep dip petroleum bearing structures and its superiority to other methods
In this paper, first the limitations of the ray-based method and the one-way wave-field extrapolation migration (WEM) in imaging steeply dipping structures are discussed by some examples. Then a new method of the reverse time migration (RTM), used in imaging such complex structures is presented. The proposed method uses a new wave-field extrapolator called the Leapfrog-Rapid Expansion Method (L...
متن کاملAdaptive beamforming in row-column addressed arrays for 3D ultrasound imaging
In recent years, to reduce the complexity of implementation, the use of 2D arrays with restricted row-column addressing has been considered for 3D ultrasound imaging. In this paper, two methods of adaptive beamforming based on the minimum variance method are represented in such a way that the computational load is much less than using the full adaptive beamforming method. In both proposed metho...
