A Survey on Detection, Classification, and Tracking of Aerial Threats using Radar and Communications Systems
Radar systems are further divided into conventional and modern radar systems, while communication systems can be used for joint communications and sensing (JC&S) in active mode and act as a source of illumination to passive radars for DCT-U.
Impact of 3D Antenna Radiation Pattern in UAV Air-to-Ground Path Loss Modeling and RSRP-based Localization in Rural Area
By analyzing reference signal received power (RSRP) using path loss models that account for antenna patterns, we observed that our measurement results, obtained at different UAV heights, aligned well with the two-ray path loss model when incorporating the measured antenna pattern.
Kriging-Based 3-D Spectrum Awareness for Radio Dynamic Zones Using Aerial Spectrum Sensors
In particular, we introduce a 3D Kriging interpolation technique that uses realistic 3D correlation models of the signal power extracted from extensive measurements carried out at the NSF AERPAW platform.
Propagation Measurements and Coverage Analysis for mmWave and Sub-THz Frequency Bands with Transparent Reflectors
The emerging 5G and future 6G technologies are envisioned to provide higher bandwidths and coverage using millimeter wave (mmWave) and sub-Terahertz (THz) frequency bands.
SDR-Based 5G NR C-Band I/Q Monitoring and Surveillance in Urban Area Using a Helikite
In this paper, we report experimental results in collectting and processing 5G NR I/Q samples in the 3. 7~GHz C-band by using software-defined radio (SDR)-mounted helikite.
LTE I/Q Data Set for UAV Propagation Modeling, Communication, and Navigation Research
However, there are limited data sets to study the coverage of cellular technologies for UAV flights at different altitudes and develop machine learning (ML) techniques for improving UAV communication and navigation.
Spectrum Monitoring and Analysis in Urban and Rural Environments at Different Altitudes
Due to the scarcity of spectrum resources, the emergence of new technologies and ever-increasing number of wireless devices operating in the radio frequency spectrum lead to data congestion and interference.
A Survey on Detection, Tracking, and Classification of Aerial Threats using Radars and Communications Systems
Finally, limitations of radar systems and comparison with other techniques that do not rely on radars for detection, tracking, and classification of aerial threats are provided.
AERIQ: SDR-Based LTE I/Q Measurement and Analysis Framework for Air-to-Ground Propagation Modeling
In this paper, we introduce AERIQ: a software-defined radio (SDR) based I/Q measurement and analysis framework for wireless signals for aerial experimentation.
Indoor Propagation Measurements with Sekisui Transparent Reflectors at 28/39/120/144 GHz
The measurement results suggest that the transparent reflector, apart from an obvious advantage of transparency, has a higher penetration loss than the common indoor materials (excluding metal) and performs similarly to metal in terms of reflection.
Out-of-Zone Signal Leakage Sensing in Radio Dynamic Zones
In order to operate an RDZ, use of a real-time spectrum monitoring system carries critical importance.
60 GHz Outdoor Propagation Measurements and Analysis Using Facebook Terragraph Radios
In this work, we investigated the propagation and scattering behavior of 60 GHz mmWave signals in outdoor environments at a travel distance of 98 m for an aerial link (rooftop to rooftop), and 147 m for a ground link (light-pole to light-pole).
Experimental Study of Outdoor UAV Localization and Tracking using Passive RF Sensing
First, the Keysight sensor detects the UAV by comparing the received RF signature with various other UAVs' RF signatures in the Keysight database using an envelope detection algorithm.
Sub-Terahertz and mmWave Penetration Loss Measurements for Indoor Environments
In this work, we measured the penetration loss and the attenuation of several common constructional materials at mmWave (28 and 39 GHz) and sub-THz (120 and 144 GHz) bands.
28 GHz Indoor and Outdoor Propagation Analysis at a Regional Airport
What is more, in non-line-of-sight (NLOS) propagation, the attenuation of mmWave is larger compared to the lower frequencies, which can seriously degrade the performance.
Channel Prediction for mmWave Ground-to-Air Propagation under Blockage
Ground-to-air (GA) communication using unmanned aerial vehicles (UAVs) has gained popularity in recent years and is expected to be part of 5G networks and beyond.
EMR: A New Metric to Assess the Resilience of Directional mmWave Channels to Blockages
Millimeter-wave (mmWave) communication systems require narrow beams to increase communication range.
