Target Signature Extraction Using Truncated Singular Value Decomposition for Electronic Protection

2021 IEEE Radar Conference (RadarConf21), 2021
Recent studies show that jamming suppression can be performed using modified matched filters that are matched to the transmit waveform - target response (TWTR). In many radar applications the target backscattering is reduced to a scalar factor, which is mainly related to the radar cross section (RCS).

Approximate convolution using partitioned truncated singular value decomposition filtering

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
In many signal processing applications it is necessary to perform large convolutions in real-time. For systems where an exact convolution is too complex we propose an approximation using a partitioned truncated singular value decomposition (PTSVD) filter.

TP Model Transformation Via Sequentially Truncated Higher‐Order Singular Value Decomposition

Asian Journal of Control, 2014
AbstractThe sequentially truncated higher‐order singular value decomposition (ST‐HOSVD) is applied to a tensor product (TP) model transformation instead of the compact form of HOSVD (CHOSVD). The goal is to reduce computational cost in the transformation.

Singular value decomposition for the truncated Hilbert transform

Inverse Problems, 2010
Starting from a breakthrough result by Gelfand and Graev, inversion of the Hilbert transform became a very important tool for image reconstruction in tomography. In particular, their result is useful when the tomographic data are truncated and one deals with an interior problem.

Interior reconstruction using the truncated Hilbert transform via singular value decomposition

Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2008
The state-of-the-art technology for theoretically exact local computed tomography (CT) is to reconstruct an object function using the truncated Hilbert transform (THT) via the projection onto convex sets (POCS) method, which is iterative and computationally expensive.

Asymptotic behaviour of the singular values for the truncated Hilbert transform

2013 IEEE Nuclear Science Symposium and Medical Imaging Conference (2013 NSS/MIC), 2013
We present new results on the singular value decomposition (SVD) of the truncated Hilbert transform (THT). The THT problem consists in recovering a function f(x) with support on an interval [a 2 , a 4 ] from the knowledge of its Hilbert transform over an interval [a 1 , a 3 ] which overlaps with the support of f, i.e. a 1 2 3 4 . This problem has

Truncated singular value decomposition method for calibrating a Stokes polarimeter

SPIE Proceedings, 2007
We present a method for calibrating polarimeters that uses a set of well-characterized reference polarizations and makes no assumptions about the optics contained in the polarimeter other than their linearity. The method requires that a matrix be constructed that contains the data acquired for each of the reference polarization states and that this ...

On frequency weighted balanced truncation technique retaining Hankel singular values

Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005
A modification to Lin and Chiu's technique of frequency weighted balanced truncation is presented. The method is based on simultaneously diagonalizing the frequency weighted controllability and observability Gramians. Instead of obtaining the reduced order models from the truncated frequency weighted balanced realization as in the conventional ...
