Physical 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]
Space 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]
Remote 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.

Camille Drevet : Les Annamites chez eux (1928) ou l’écriture de l’urgence
Viatica, 2018 Les Annamites chez eux, published in 1928 by Camille Drevet, has a strong link with what is called here “emergency writing”. Sketching a portrait of this feminist, the article examines the theoretical viewpoints surrounding the specific case of female ...

Radar detection and speed estimation of high‐speed targets using phase‐modulated waveforms
Electronics Letters, 2023 Specifying parameters of high‐speed targets as range and velocity in radar systems operating with phase‐modulated signals is a problematic process because of the serious effect of high Doppler frequency on these types of waveforms.
