Welcome to IEEE AESS Tutorial XV
We are pleased to offer the 15th issue of IEEE AES tutorials,
Tutorial XV, to members of the IEEE AESS. Three kinds of
tutorial articles are traditionally offered: a primer on an established
topic, an introduction to a topic ofemerging importance,
and a survey ofan established technical area. In all three cases,
authors are for the most part noted experts willing to share
their knowledge and experience in a written field guide. In
Tutorial XV, the first and fourth articles address topics of
emerging importance, while the second and third articles focus
on established technical areas.
The first article, " Monocular visual autonomous landing
system for quadcopter drones using software in the loop, "
addresses the autonomous landing of multirotor drones in
social and industrial applications. Safe autonomous landing
is a capability that is essential to achieve the full potential of
multirotor drones. However, the implementation and testing
of this capability on physical platforms is risky and resource
intensive. In order to reduce the risks of the physical testing
stage, a software-in-the-loop methodology is used to
develop a monocular visual autonomous landing system that
efficiently lands a quadcopter drone on a predefined landing
pad. The proposed monocular vision-only landing system
pad is implemented in an F450 quadcopter drone with the
computational capabilities of an Odroid XU4 embedded
processor.
The second article, " A survey on the applications of
convolutional neural networks for synthetic aperture radar:
Recent advances, " reviews the use of convolutional neural
networks (CNNs) for the analysis of synthetic aperture radar
(SAR) data. Complex-valued CNNs that exploit phase information
embedded in SAR images are extensively reviewed.
Automatic target recognition, land use and land cover classification,
segmentation, change detection, object detection,
and image denoising are addressed. Special emphasis is
given to practical techniques such as data augmentation and
transfer learning. This tutorial concludes with open challenges
and future research directions for CNNs in SAR.
The third article, " A rationale for backprojection in spotlight
synthetic aperture radar image formation, " addresses
treatment ofthe backprojection for spotlight SAR image formation.
The treatment that is unique, elementary, and
detailed begins with the wave equation and melds wave concepts
with signal processing using a compact and consistent
notation throughout. Since the tutorial provides a somewhat
different point of view from the usual presentation, engineers
who have worked in the field may find it valuable.
Certainly, engineers from different fields should value the
presentation of the engineering concepts connecting the
wave theory and signal processing.
The fourth article, " Detecting a target with quantum
entanglement, " addresses the emerging and somewhat controversial
topic of quantum radar. Over the last decade,
research activity has been focused on the use of quantum
entanglement as a resource for remote target detection. The
results from the application of quantum optics and quantum
information theory are often obscure to radar engineers. The
purpose of this tutorial is to remove this obscurity. As such,
it contains a review of the main advances in quantum radar
literature accompanied by a thorough introduction of the
quantum optics and quantum information theory.
Good tutorial articles in the areas of interest to AESS
members are in great demand. If you have a topic of interest
and a potential author, please contact me to nominate a tutorial.
Self-nominations are also welcome. All tutorials are
subjected to peer review to ensure the quality of our articles.
Tutorials are reviewed for clarity of presentation, relevance,
correctness, and scientific merit. Explanations of complex
topics in simple (tutorial) terms are sought. Tutorials should
not include new research results. The archival home for new
research is our IEEE Transactions on Aerospace and Electronic
Systems, and submissions with new results will be
rerouted to the transactions. Likewise, interesting and
descriptive articles without significant tutorial content
should more properly be submitted to IEEE Aerospace and
Electronic Systems Magazine.
