DESCRIPTION;LANGUAGE=en-US:Abstract:\nTitle: Advancing Unmanned Aircraft Sy
stem: A New Paradigm for UAS/UGV-based Precision Agriculture and Environme
ntal Sensing using Recycled Frequency Spectrum\nAccurate measurement of so
il moisture (SM) has a significant impact on agricultural production\, hyd
rological modeling\, forestry\, waste management\, and other environmental
fields. Particularly in precision agriculture (PA)\, high spatio-temporal
resolution information about surface SM is crucial. However\, the use of
invasive SM probes and other sensors is expensive and requires extensive m
anpower. Moreover\, these intrusive measurement techniques provide point m
easurements and are unsuitable for large agricultural fields. As an altern
ative\, this research explores the remote sensing of surface SM by utilizi
ng the surface reflectivity estimated from global navigation satellite sys
tems - reflectometry (GNSS-R) data acquired through smartphones and off-th
e-shelf\, cost-effective GNSS receivers. To estimate surface reflectivity\
, GNSS receivers are attached underneath an unmanned aircraft system (UAS)
\, which flies over agricultural fields. The estimated surface reflectivit
y is directly proportional to the soil dielectric permittivity and can be
translated to volumetric soil moisture (VSM). Additionally\, this research
investigates a fully custom UAS-based dual-polarized (H-pol and V-pol) L-
band microwave radiometric measurement technique over agricultural areas t
o estimate surface brightness temperature (𝑇𝐵). The radiometer measu
res surface emissivity as 𝑇𝐵\, allowing for the estimation of surfac
e SM while considering the detection and removal of radio frequency interf
erence (RFI) from the radiometric measurements. This surface emissivity ca
n be derived from surface reflectivity with the relationship of (Emissivit
y = 1 - Reflectivity)\nBeyond soil moisture estimation\, this research fur
ther expands GNSS remote sensing by investigating a GNSS Transmissometry (
GNSS-T) approach to estimate vegetation optical depth (VOD) over large-sca
le forestry regions. This method utilizes multi-angle GNSS signals transmi
tted from global navigation satellite constellations and received by unman
ned ground vehicle (UGV)-mounted GNSS-T sensors\, enabling the assessment
of vegetation water content and biomass. Furthermore\, this research expl
ores the coexistence of 5G active communication with passive L-band microw
ave radiometry\, addressing the growing concern of RFI contamination in re
mote sensing measurements.\nIn summary\, this study highlights the utiliza
tion of smartphones and semi-custom GNSS receivers in combination with UAS
-based GNSS-R techniques and UAS-based L-band microwave radiometry for est
imating surface reflectivity and 𝑇𝐵. Additionally\, it advances GNSS
-T-based VOD estimation and assesses the challenges and mitigation strateg
ies for passive radiometry in the presence of 5G active transmissions\, co
ntributing to the development of robust and scalable environmental sensing
technologies.\n\nBio:\nDr. Farhad is a Postdoctoral Fellow at the Univers
ity of Georgia. He received his Ph.D. from Mississippi State University. H
e specializes in Unmanned Aerial Systems (UAS)\, and UAS-based microwave r
emote sensing\, applied electromagnetics\, and precision agriculture. His
research focuses on designing autonomous UAS platforms and sensing systems
that integrate environmental data with signals of opportunity to advance
precision agriculture. Dr. Farhad is a recipient of the NASA Early Career
Research (ECR) Award FINESST22\, securing a $150\,000 grant\, and has been
awarded with the 2024 Bagley College of Engineering Best Graduate Researc
h Award\, Hall of Fame Student Award\, and the 2023 ECE Best Graduate Rese
arch Award at Mississippi State University. His work advances autonomous r
emote sensing technologies for applications in agriculture\, forestry\, an
d environmental monitoring.\n\n\n_________________________________________
