Design and evaluation of a compact harmonic transponder for insect tracking

A Lavrenko, B Litchfield, G Woodward… - IEEE Microwave and …, 2020 - ieeexplore.ieee.org
Passive harmonic transponders are used in applications where weight and size restrictions
are prohibitive to the use of active radio transmitters, eg, for insect tracking. A typical …

Harmonic radar with adaptively phase-coherent auxiliary transmitters

A Lavrenko, JK Cavers… - IEEE transactions on …, 2022 - ieeexplore.ieee.org
In harmonic radar (HR), the transmitter illuminates a nonlinear target (the tag), causing the
return signal to consist of harmonics at multiples of the transmitted carrier frequency. Of them, …

Design and analysis of compressive antenna arrays for direction of arrival estimation

M Ibrahim, V Ramireddy, A Lavrenko, J König… - Signal Processing, 2017 - Elsevier
In this paper we investigate the design of compressive antenna arrays for narrow-band
direction of arrival (DOA) estimation that aim to provide a larger aperture with a reduced …

Two‐region model for harmonic radar transponders

A Lavrenko, J Cavers - Electronics Letters, 2020 - Wiley Online Library
Harmonic radar transponders are passive RF tags that produce a harmonic response when
illuminated with an RF signal. With a Schottky diode as the main component, the tag current …

Effects of bistatic operation in harmonic radar

A Lavrenko - 2022 19th European Radar Conference (EuRAD), 2022 - ieeexplore.ieee.org
Harmonic radar systems are used to interrogate, or track a location of, passive nonlinear
targets in highly cluttered environments, and they are notorious for their poor power efficiency …

Compact low-cost FMCW harmonic radar for short range insect tracking

G Storz, A Lavrenko - 2020 IEEE International Radar …, 2020 - ieeexplore.ieee.org
We present two frequency modulated continuous wave (FMCW) harmonic radar prototypes
for application in insect tracking. They respectively operate in the maritime radar allocations …

On the SNR variability in noisy compressed sensing

A Lavrenko, F Römer, G Del Galdo… - IEEE Signal Processing …, 2017 - ieeexplore.ieee.org
Compressed sensing (CS) is a sampling paradigm that allows us to simultaneously measure
and compress signals that are sparse or compressible in some domain. The choice of a …

Autonomous swarm of UAVs for tracking of flying insects with harmonic radar

A Lavrenko, Z Barry, R Norman… - 2021 IEEE 93rd …, 2021 - ieeexplore.ieee.org
In this paper, we present a design and first proof-of-concept test results of a distributed radio-localization
system for tracking of moving targets with a swarm of drones. In particular, we …

Compact folded meander-line harmonic tag antenna for insect tracking

A Kumar, A Lavrenko - 2023 17th European Conference on …, 2023 - ieeexplore.ieee.org
This awork presents a novel single layer dual-band meander-line harmonic tag antenna
implemented on a thin flexible substrate. The proposed prototype consists of folded asymmetric …

On the use of additional transmitters for increasing detection range in harmonic radar

A Lavrenko, S Pawson, J Cavers - 2019 13th International …, 2019 - ieeexplore.ieee.org
Harmonic radar is commonly used in localisation and tracking applications where weight and
size restrictions do not allow the use of active radio transmitters. It relies on the operation of …
