Compressed sensing using a non-uniformly sampled range-azimuth dictionary [PDF]
MATEC Web of Conferences, 2019 FM-bats are known to be able to sense the environment by echolocation. In this paper, assuming the objects in the environment can be characterized by a sparse representation of the echoes in range and azimuth, a compressed sensing algorithm using a range-

Ambiguity and Social Interaction [PDF]
, 2005 We present a non-technical account of ambiguity in strategic games and show how it may be applied to economics and social sciences. Optimistic and pessimistic responses to ambiguity are formally modelled.

Phase Imbalance Estimation for Azimuth Multi-Channel ScanSAR System
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 The new concept of combining the azimuth multichannel synthetic aperture radar (SAR) system with the Scan mode was put forward to meet the requirements of future developments in high-resolution and ultrawide-swath SAR design. However, the phase imbalance

Testing dynamic consistency and consequentialism under ambiguity [PDF]
, 2020 Accounting for ambiguity aversion in dynamic decisions generally implies that either dynamic consistency or consequentialism must be given up. To gain insight into which of these principles better describes people's preferences, we tested them using a ...

Multi-Channel SAR System Design for HRWS and GMTI in Low PRF
IEEE Access, 2020 High-resolution and wide-swath (HRWS) is an important challenge in synthetic aperture radar (SAR). Combined SAR with array, the azimuth dual-channel SAR configuration achieves high azimuth resolution and HRWS in low Pulse repetition frequency (PRF) by ...

Real‐Time Ferroelectric Domain Wall Dynamics During Electric Poling and Depoling
Advanced Science, EarlyView.Real‐time visualization of domain wall dynamics during alternating‐current poling, direct‐current poling, and electrical depoling in relaxor‐PT ferroelectric single crystals reveals distinct field‐dependent pathways and strong path dependence. Instant polarized light microscopy uncovers reversible domain wall nucleation, motion, and reconfiguration ...
