Channel Rank Improvement in Urban Drone Corridors Using Passive Intelligent Reflectors
2023 IEEE AEROSPACE CONFERENCE.
TL;DR:
The results at 6 GHz, 28 GHz, and 60 GHz show that the proposed approach increases the average rates for all frequency bands for a given drone corridor when compared with the environment with no IRSs present, and IRS-aided channels perform close to each other at sub-6 and mmWave bands.

Comparative Analysis of Radar-Cross-Section-Based UAV Recognition Techniques
IEEE SENSORS JOURNAL, 22(18), 17932–17949.
author keywords: Deep learning (DL); machine learning (ML); radar cross section (RCS); statistical learning (SL); target identification and recognition; unmanned aerial vehicles (UAVs)
TL;DR:
The study shows that, while the average accuracy of all the algorithms increases with the signal-to-noise ratio (SNR), the ML algorithm achieved better accuracy than the SL and DL algorithms.

Coverage Probability Analysis of Passive Reflectors in Indoor Environments
IEEE COMMUNICATIONS LETTERS, 26(10), 2287–2291.
author keywords: Scattering; Signal to noise ratio; Probability density function; Metals; Mathematical models; Antenna arrays; Transmitting antennas; B5G; indoor coverage; mmWave; non-line-of-sight (NLOS); sub-THz; transparent reflectors
TL;DR:
This letter considers an indoor open-door scenario, where the LoS link is blocked by the walls for receivers inside the room, and the Coverage can only be achieved via an NLoS link through a passive reflector, and analytically derive closed-form equations of the reflection visibility probability and the coverage probability.

Radar Cross Section Based Statistical Recognition of UAVs at Microwave Frequencies
IEEE TRANSACTIONS ON AEROSPACE AND ELECTRONIC SYSTEMS, 58(1), 27–46.
author keywords: Radar cross-sections; Radar; Radar imaging; Target recognition; Signal to noise ratio; Drones; Propellers; Akaike information criterion (AIC); automatic target recognition (ATR); Bayesian information criterion (BIC); classification; compact-range chamber; detection; radar cross-section (RCS); unmanned aerial vehicle (UAV)
TL;DR:
From the model selection analysis, it is observed that the lognormal, generalized extreme value, and gamma distributions are most suitable for modeling the RCS of the commercial UAVs while the Gaussian distribution performed relatively well and the best UAV radar statistics forms the class conditional probability densities for the proposed UAV statistical recognition system.

Ray Tracing Analysis of Sub-6 GHz and mmWave Indoor Coverage with Reflecting Surfaces
2022 IEEE RADIO AND WIRELESS SYMPOSIUM (RWS), pp. 160–163.
author keywords: 28 GHz; 60 GHz; indoor propagation; mmWave; ray tracing; reflecting surfaces
TL;DR:
The results showed that ray tracing solutions are consistent with theoretical calculations, and using reflective walls significantly improves average received power and connectivity at mmWave bands, e.g., for the given floor plan, coverage increases from 86% to 97.5% at 60 GHz band.

Base Station and Passive Reflectors Placement for Urban mmWave Networks
IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, 70(4), 3525–3539.
author keywords: Three-dimensional displays; Planning; IP networks; Quality of service; Buildings; Optimization; Bibliographies; 5G; coverage enhancement; GNB location optimization; maximum coverage; metallic reflectors; MmWave
TL;DR:
Simulation results show that considering the first-order reflections in planning the mmWave network helps reduce the number of PMRs required to cover the NLoS area, which in turn reduces the deployment cost.
