GPR Image Decluttering Using Matrix Pencil Based Trace Filtering Method
Ground Penetrating Radar (GPR) measurements can suffer from large amount of noise and clutter. Current methods, such as time gating and background averaging, mostly applied to remove reflections from air-ground interface do not perform well when removal of extraneous, very strong and non-uniform clutter signals originating from the objects in the surveyed area other than the target is needed. T...
متن کاملFault Tolerant Matrix Pencil Method for Direction of Arrival Estimation
Continuing to estimate the Direction-of-arrival (DOA) of the signals impinging on the antenna array, even when a few elements of the underlying Uniform Linear Antenna Array (ULA) fail to work will be of practical interest in RADAR, SONAR and Wireless Radio Communication Systems. This paper proposes a new technique to estimate the DOAs when a few elements are malfunctioning. The technique combin...
متن کاملA Matrix Pencil Algorithm Based Multiband Iterative Fusion Imaging Method
Multiband signal fusion technique is a practicable and efficient way to improve the range resolution of ISAR image. The classical fusion method estimates the poles of each subband signal by the root-MUSIC method, and some good results were get in several experiments. However, this method is fragile in noise for the proper poles could not easy to get in low signal to noise ratio (SNR). In order ...
متن کاملOn the Nearest Singular Matrix Pencil
Given a regular matrix pencil A + μE, we consider the problem of determining the nearest singular matrix pencil with respect to the Frobenius norm. We present new approaches based on the solution of matrix differential equations for determining the nearest singular pencil A+∆A+ μ(E +∆E), one approach for general singular pencils and another one such that A+∆A and E + ∆E have a common left/right...
متن کاملEstimating two-dimensional frequencies by matrix enhancement and matrix pencil
A new method, called the matrix enhancement and matrix pencil (MEMP) method, is presented for estimating twodimensional (2-D) frequencies. The MEMP method first constructs an enhanced matrix from the data samples, and then uses the matrix pencil approach to extract out the 2-D sinusoids from the principal eigenvectors of the enhanced matrix. The MEMP method yields the estimates of the 2-D frequ...
