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

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

MIMO Radar Ambiguity Properties and Optimization Using Frequency-Hopping Waveforms [PDF]
, 2008 The concept of multiple-input multiple-output (MIMO) radars has drawn considerable attention recently. Unlike the traditional single-input multiple-output (SIMO) radar which emits coherent waveforms to form a focused beam, the MIMO radar can transmit ...

On the Derivation of Volume Decorrelation From TanDEM-X Bistatic Coherence
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 The bistatic interferometric coherence is affected by different sources of error, among which volume decorrelation, which quantifies the amount of noise caused by volume scattering mechanisms.
