Meetings With One of the Fathers of Radar Through His Daughter, the Princess Elettra Marconi
the homepage of the Leonardo website [13], which
included a short video of the interview. The total number
of page views up to March 2022 was 2245 with 87% from
Italy, followed by 6.4% from the United States, and 2.5%
from the U.K. These accesses were 50.5% from mobile
devices, 48% from desktop, and 1.5% from tablets.
When published, it was the second most visited item
on the Leonardo site, with the second highest average
viewing time and over 20% of users responded to the article

OUTLOOK FOR THE RADAR
Searching Google on 6 July 2022 with the word " radar, "
we find circa 1250,000,000 references. There is no doubt
that the radar has made a significant impact in the world in
these past 100 years and more.
The following is a not-exhaustive list of its many current
applications:
Civilian-Commercial
➢ air traffic control (ATC) for en-route, approach and terminal
area;
➢ surface monitoring of air traffic in the airport by different
classes of sensors (surface movement radar, multilateration);
➢
weather radar;
➢ vessel traffic surveillance (VTS) for maritime
awareness;
➢ automotive, anticollision for cars;
➢ radars for medical applications;
➢ ground penetrating radar for geology, land-slides, gas
pipe detection, archaeology, mine detection;
➢ commercial applications.
Defense
➢ passive surveillance (passive coherent location radar,
electronic support measure);
➢ homeland protection (counter-unmanned aerial system);
➢ air defense (surveillance, tracking, weapon guidance);
➢ anti-tactical ballistic missile (ATBM) defense;
➢ mitigation of hypersonic threat;
➢ naval defense (surveillance, tracking, weapon guidance).
Space Borne
➢ synthetic aperture radar (SAR) imaging;
➢ space-borne altimetry;
➢ space-borne scatterometry;
➢ space-borne remote sensing (crop, hydrology, geodesy,
3-D topography, archaeology, astronomy, defense);
➢ weather monitoring and prediction;
➢ planetary exploration and astronomy;
➢ space situational awareness and tracking;
➢ acquisition and tracking of satellites in the re-entry
phase, monitoring of space debris.

The current state ofevents for the Earth has an impact on
everybody, including us: the radar engineering community.
We can say that the radar development has greatly contributed
to the birth ofdigitalization and will continue to do so.
In this new vision of how we are to contribute now
and in the future, here are some examples where radar
technology might help [18] in relation to the 17 sustainable
development goals established by the United
Nations [19].
Impact on Digital Economy
➢ 5G/6G;
➢ broadband interconnectivity;
➢ digital twins technology.
Impact on Sustainable Economy
➢ weather radar, radar biology;
➢ radio-echo sounder.
Impact on Green Economy
➢ passive radar;
➢ multirole radar system.
Impact on Space Economy
➢ monitoring the Earth;
➢ space situational awareness;
➢ suborbital flights.
Impact on Commercial Market
➢ automotive;
➢ unmanned ground vehicle (UGV);
➢ health care and emergency.
Continue to Contribute to
➢ air traffic control safety and fluency;
➢ national and NATO security.
CONCLUSION
Looking at Marconi's achievements, as well as reflecting on
the memories and studies of his daughter Princess Elettra,
his career consisted of a series of important milestones of
never-ending exploration, driven by a global vision and a
forward-looking attitude. The same features that are now the
basis ofour way of " doing business, " in which research and
innovation guide the evolution of technologies over time,
for the benefit ofpeople, society, and the planet [13].
