Enabling Joint Communication and Radar Sensing in Mobile Networks—A Survey [PDF]

IEEE Communications Surveys and Tutorials, 2020
Mobile network is evolving from a communication-only network towards one with joint communication and radar/radio sensing (JCAS) capabilities, that we call perceptive mobile network (PMN).

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

Automotive Radar — From First Efforts to Future Systems

IEEE Journal of Microwaves, 2021
Although the beginning of research on automotive radar sensors goes back to the 1960s, automotive radar has remained one of the main drivers of innovation in millimeter wave technology over the past two decades.

Foundations of MIMO Radar Detection Aided by Reconfigurable Intelligent Surfaces [PDF]

IEEE Transactions on Signal Processing, 2021
A reconfigurable intelligent surface (RIS) is a nearly-passive flat layer made of inexpensive elements that can add a tunable phase shift to the impinging electromagnetic wave and are controlled by a low-power electronic circuit. This paper considers the

Horus—A Fully Digital Polarimetric Phased Array Radar for Next-Generation Weather Observations

IEEE Transactions on Radar Systems, 2023
Weather radars have become indispensable to meteorologists and the general public for both understanding and awareness of high-impact weather events and as part of the operational warning infrastructure. In the U.S., the operational weather radar network

TanDEM-X Long-Term System Performance After 10 Years of Operation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The TanDEM-X mission, formed by the TanDEM-X satellite in cooperation with its almost identical twin TerraSAR-X (TSX), has mainly been designed to acquire bistatic synthetic aperture radar (SAR) images of the Earth. Initiated in 2010, the primary mission

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.

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 ...
