Compressed Sensing for Multistatic Radar Systems with Arbitrary Block Codes
(2015)Multistatic radar systems with multiple elements at transmitting and/or receiving side permit multiple target observations from different viewpoints providing various advantageous. In an environment with multiple transmitters ... -
Analysis of detection performance of incoherent range walk compensation for passive radar
(2015)This paper analyzes the performance of an incoherent range walk compensation method for passive radar systems. The method utilizes the velocity information in the range-Doppler map, and no detection before compensation ... -
The Effect of Internal Wave-Related Features on Synthetic Aperture Sonar
(2015)In October 2012, the Centre for Maritime Research and Experimentation (CMRE, La Spezia, Italy) conducted trials from the NATO research vessel (RV) Alliance, off Elba Island, Italy. During this trial, data were collected ... -
Selective adsorption of lead, copper and antimony in runoff water from a small arms shooting range with a combination of charcoal and iron hydroxide
(2015)Metals and metalloids from ammunition residues at small arms shooting ranges leach into the soil and surrounding watercourses and may pose a threat to exposed wildlife and humans. To reduce the potential impact of heavy ... -
Chemoselective O-acylation of hydroxyamino acids and amino alcohols under acidic reaction conditions: History, scope and applications
(2015)Amino acids, whether natural, semisynthetic or synthetic, are among the most important and useful chiral building blocks available for organic chemical synthesis. In principle, they can function as inexpensive, chiral and ... -
Temporal stability of X-band single-pass InSAR heights in a spruce forest: Effects of acquisition properties and season
(2015)We investigated the stability of TanDEM-X interferometric synthetic aperture radar (InSAR) heights across eight repeated acquisitions. With InSAR height we mean the height above ground of the scattering phase center. We ... -
Uniform semiglobal exponential stability of integral line-of-sight guidance laws
(2015)This paper proves that an integral line-of-sight guidance law for path following control of underactuated marine vessels provides uniform semiglobal exponential stability. The stability result is stronger than what has ... -
A Multiscale Wavelet-Based Test for Isotropy of Random Fields on a Regular Lattice
(2015)A test for isotropy of images modeled as stationary or intrinsically stationary random fields on a lattice is developed. The test is based on the wavelet theory, and can operate on the horizontal and vertical scale of ... -
Harmonic Synthetic Aperture Radar Processing
(2015)We review the basic concept of frequency-modulated continuous wave (FMCW) and describe how such a radar system can be used in a harmonic radar concept. It is argued that synthetic aperture radar (SAR) for FMCW harmonic ... -
In-Body to On-Body Ultrawideband Propagation Model Derived from Measurements in Living Animals
(2015)Ultra wideband (UWB) radio technology for wireless implants has gained significant attention. UWB enables the fabrication of faster and smaller transceivers with ultra low power consumption, which may be integrated into ... -
A survey of dioxin-like contaminants in fish from recreational fishing
(2015)The dioxin and dioxin-like compounds are regarded as one of the most toxic group of environmental contaminants. Food for the commercial market is regularly monitored for their dioxin levels and the concentration allowed ... -
Robust Identification of Concealed Dangerous Substances by Spectral Correlation of Terahertz Transmission Images
(2015)Terahertz (THz) images containing spectral information in each pixel are recorded in transmission mode using a fiber-coupled time-domain spectroscopy system. The images are acquired by mounting a sample holder on an x-y ... -
Disruptive camouflage tricks the human eye - a study of detection times of two near-similar targets in natural backgrounds
(2015)Our understanding of camouflage, in military as well as in evolutionary perspectives, has been developing over the last 100 years. In that period of time several underlying principles have emerged. It has turned out in the ... -
A hybrid recorded-synthetic sonar data set for validation of ASW classification algorithms
(2015)Modern anti-submarine warfare sonars are often designed with narrow beamwidths and wide frequency bandwidths in order to maximize spatial resolution and sonar performance. A known issue for high-resolution sonars in littoral ... -
Are team personality and climate related to satisfaction and software quality? Aggregating results from a twice replicated experiment
(2015)Context Research into software engineering teams focuses on human and social team factors. Social psychology deals with the study of team formation and has found that personality factors and group processes such as team ... -
A Radon-Transform-Based Image Noise Filter - With Applications to Multibeam Bathymetry
(2015)This paper describes a linear-image-transform-based algorithm for reducing stripe noise, track line artifacts, and motion-induced errors in remote sensing data. Developed for multibeam bathymetry (MB), the method has also ... -
Supralethal poisoning by any of the classical nerve agents is effectively counteracted by procyclidine regimens in rats
(2015)A treatment regimen consisting of HI-6, levetiracetam, and procyclidine (termed the triple regimen) has previously been shown to work as a universal therapy against soman poisoning in rats, since it has capacities to ... -
Identification of airborne bacteria by 16S rDNA sequencing, MALDI-TOF MS and the MIDI microbial identification system
(2015)The aim of this study was to collect and identify airborne bacteria in Norway, Sweden and Finland and to compare three different technologies for identifying collected airborne bacterial isolates: the “gold standard” method ... -
Predator sound playbacks reveal strong avoidance responses in a fight strategist baleen whale
(2015)Anti-predator strategies are often defined as ‘flight’ or ‘fight’, based upon prey anatomical adaptations for size, morphology and weapons, as well as observed behaviours in the presence of predators. The humpback whale ... -
Robust identification of concealed dangerous substances using THz imaging spectroscopy
(2015)False alarm rates must be kept sufficiently low if a method to detect and identify objects or substances is to be implemented in real life applications. This is also true when trying to detect and identify dangerous ...
