elcome to our April issue. I write this in March from the northeast US, which means that we've had to
put away our February T-shirts and golf clubs in favor of parkas and snow shovels. Good (weather)
luck to us all for the Spring! I hope to see many of you at the Radar Conference in Oklahoma City
in April - the AESS Board of Governors has its spring meeting there, which I'm sure is an added attraction
for many of you.
It's my pleasure to introduce a full and interesting issue of contributed papers this month - we are getting so many excellent papers, both contributed and Special Issue (invited), that sometimes there is a delay
to publication. We apologize that some spend time "in the queue". First, Wahl & Turkoglu from San Jose
State have given us Nonlinear Receding Horizon Control-Based Real-Time Guidance, Navigation, and
Control Architecture for Launch Vehicles. As the title promises, the article suggests an RHC strategy for
space vehicle guidance, and in fact gives a nice historical context for the solution. The article is rather more
mathematical than the typical magazine offering; but, well, control is mathematical. Huang & Lin from
Aphelion Orbitals in Florida offer Fully Optical Spacecraft Communications: Implementing an OmnidiPeter Willett
rectional PV-Cell Receiver and 8 Mb/s LED Visible Light Downlink With Deep Learning Error Correction
that suggests use of the extant on-board photovoltaic systems for the visible-light communication (VLC)
uplinks. There are significant challenges, perhaps the greatest being the high raw error rate caused by low SNR and non-coherent demodulation; the authors propose a deep-learning decoding strategy. Coupled with a LED downlink this may be an economical product for upcoming
cubesats.
Waseem & Sadiq from the Satellite Research and Development Centre in Pakistan have given us Application of Model-Based Systems
Engineering in Small Satellite Conceptual Design-A SysML Approach which is a nice systems engineering case study. The article describes
the experience of use of SysML, which is a modeling language used to design and verify systems ... and systems of systems. Since many of
our members are concerned with systems engineering as a large part of their daily work, and since the small-satellite focus is emerging, we
hope the reader will find this article timely and useful. And as air traffic control is indeed a large scale "system," the theme is continued in
Simulation Modelling of Traffic Collision Avoidance System With Wind Disturbance by Tang, Zhu & Fan, all from the National University of
Defense Technology but with joint appointments at Barcelona and the Imperial College London. The application is air-traffic TCAS, and the
focus is on the very necessary system description.
A large team of authors from Airbus and the Universities of Valencia (Spain), Erlangen-Nurnberg (Germany) and Udine (Italy) have given
us Multifunctional and Compact 3D FMCW MIMO Radar System With Rectangular Array for Medium-Range Applications. This is a particularly nice article that is exactly at the right technical level. Its title describes the subject, but only hints at the data fusion aspect: a camera also
forms part of the system and aids considerably in tracking and classification. Further, this fusion facilitates change detection, which with its
small size and economical design makes the system nicely suited for area protection or for UAV mounting.
Finally, some words about the life of radar legend Philip Mayne Woodward, who passed from us on January 30 at age 98. Dr. Woodward's
niece Suzette Woodward and colleague Susan Bond have kindly sent us their thoughts. I think most of us know of his contributions to radar,
but his contributions to computer science (especially a language I remember fondly: Algol) and (this is surprising!) clock-making will be new
at least to many of you. Thanks, Suzette!
