Passive coherent detection and target location with multiple non-cooperative transmitters [PDF]

open access: yes, 2015
Passive bistatic radars (PBR) and passive multistatic radars (PMR) use opportunistic transmitters to detect and locate targets. In this thesis, a maritime scenario was modeled with merchant vessels serving as multiple non-cooperative opportunistic ...

Optimization of passive coherent receiver system placement [PDF]

open access: yes, 2013
Passive coherent receiver systems are a form of non-monostatic radar (NMR) that use active emitters of opportunity (digital television, cell phone systems, and other types of emissions) as a source of reflected target energy.

Approximate maximum likelihood estimation of two closely spaced sources [PDF]

open access: yes, 2014
The performance of the majority of high resolution algorithms designed for either spectral analysis or Direction-of-Arrival (DoA) estimation drastically degrade when the amplitude sources are highly correlated or when the number of available snapshots is

CONUS+ Experiment

open access: yesEuropean Physical Journal C: Particles and Fields
The CONUS+ experiment aims to detect coherent elastic neutrino-nucleus scattering (CE $$\nu $$ ν NS) of reactor antineutrinos on germanium nuclei in the fully coherent regime, continuing on this way the CONUS physics program started at the Brokdorf ...
