Quantum Radar [PDF]

open access: yesPhysical Review Letters, 2020
We propose a quantum metrology protocol for the localization of a non-cooperative point-like target in three-dimensional space, by illuminating it with electromagnetic waves. It employs all the spatial degrees of freedom of N entangled photons to achieve an uncertainty in localization that is sqrt(N) times smaller for each spatial direction than what ...

Radar: The Cassini Titan Radar Mapper [PDF]

open access: yesSpace Science Reviews, 2004
The Cassini RADAR instrument is a multimode 13.8 GHz multiple-beam sensor that can operate as a synthetic-aperture radar (SAR) imager, altimeter, scatterometer, and radiometer. The principal objective of the RADAR is to map the surface of Titan. This will be done in the imaging, scatterometer, and radiometer modes. The RADAR altimeter data will provide

Radar-to-Radar Interference Suppression for Distributed Radar Sensor Networks [PDF]

open access: yesRemote Sensing, 2014
Radar sensor networks, including bi- and multi-static radars, provide several operational advantages, like reduced vulnerability, good system flexibility and an increased radar cross-section. However, radar-to-radar interference suppression is a major problem in distributed radar sensor networks.

Developments in target micro-doppler signatures analysis: radar imaging, ultrasound and through-the-wall radar [PDF]

open access: yes, 2013
Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Radar Aeroecology [PDF]

open access: yesRemote Sensing, 2020
Aeroecology is an emerging discipline founded by Tom Kunz and colleagues in the early 2000s to address the challenges of studying animal flight in the lower atmosphere [...]

The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]

open access: yes, 2012
We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

MIMO noise radar - matched filters and coarrays [PDF]

open access: yes, 2008
Copyright © 2008 IEEEThe noise radar concept can be extended to an array of K transmit antenna and M receive antenna. When independent noise sources are transmitted from each antenna the approach may be viewed as a special case of MIMO radar and matched ...

Distributed Radar-aided Vehicle-to-Vehicle Communication [PDF]

open access: yes, 2020
Establishing high-rate vehicle-to-vehicle (V2V) links with narrow beamwidth is challenging due to the varying network topology. A too narrow beam may miss the intended receiver, while a too broad beam leads to SNR loss.

Examination of the effect of array weighting function on radar target detectability [PDF]

open access: yes, 2010
This paper describes a methodology to assess the detectability of targets by anairborne fire control radar operating in a medium PRF mode in the presence of strongground clutter as a function of the transmitting and receiving antenna array ...
