A synthetic aperture imaging system using surface wave modes
(IEEE, 1995)
A synthetic aperture acoustic imaging system with a novel inversion algorithm is described. Data is obtained by using a transducer insonifying the sample surface at a critical angle which is excited by a short electrical ...
Lossless polar compression of g-ary sources
(IEEE, 2013)
In this paper, lossless polar compression of g-ary memoryless sources in the noiseless setting is investigated. Polar compression scheme for binary memoryless sources, introduced by Cronie and Korada, is generalized to ...
A comparison of two methods for fusing information from a linear array of sonar sensors for obstacle localization
(IEEE, 1995)
The performance of a commonly employed linear array of sonar sensors is assessed for point-obstacle localization intended for robotics applications. Two different methods of combining time-of-flight information from the ...
The discrete fractional Fourier transformation
(IEEE, 1996)
Based on the fractional Fourier transformation of sampled periodic functions, the discrete form of the fractional Fourier transformation is obtained. It is found that only for a certain dense set of fractional orders such ...
Cost-efficient approximation of linear systems with repeated and multi-channel filtering configurations
(IEEE, 1998-05)
It is possible to obtain either exact realizations or useful approximations of linear systems or matrix-vector products arising in many different applications, by synthesizing them in the form of repeated or multi-channel ...
Accurate plane-wave excitation in the FDTD method
(IEEE, 1997)
Different techniques are developed to implement plane-wave excitation on the finite-difference time-domain (FDTD) method, such as the initial-condition, the hard-source, and the connecting-condition techniques, for the ...
An efficient algorithm to extract components of a composite signal
(IEEE, 2000)
An efficient algorithm is proposed to extract components of a composite signal. The proposed approach has two stages of processing in which the time-frequency supports of the individual signal components are identified and ...
A particle swarm optimization based SAR motion compensation algorithm for target image reconstruction
(IEEE, 2010)
A new SAR motion compensation algorithm is proposed for robust reconstruction of target images even under large deviations of the platform from intended flight path. Phase error due to flight path deviations is estimated ...
Polar compressive sampling: A novel technique using polar codes
(IEEE, 2010)
Recently introduced Polar coding is the first practical coding technique that can be proven to achieve the Shannon capacity for a multitude of communication channels. Polar codes are close to Reed-Muller codes except the ...
Particle swarm optimization based channel identification in cross-ambiguity domain
(IEEE, 2010)
In this paper, a new array signal processing technique by using particle swarm optimization (PSO) is proposed to identify multipath channel parameters. The proposed technique provides estimates to the channel parameters ...
