 Sir Robert Watson-Watt (1892-1973) was a Scottish physicist and inventor who
is best known for his work in the development of radar (Radio Detection and
Ranging) technology during World War II.
Watson-Watt was born in Brechin, Scotland, and grew up in Dundee. He studied
physics at the University of St. Andrews and then worked as a meteorologist for
the British Meteorological Office. In the 1930s, he began researching the use of
radio waves to detect aircraft, in response to a request from the British Air
Ministry for a method to detect enemy planes before they reached British
airspace.
In 1935, Watson-Watt demonstrated a working prototype of his radar system,
which used pulsed radio waves to detect the presence and location of aircraft.
The system was quickly adopted by the British military and played a crucial role
in the defense of Britain during the Battle of Britain in 1940.
Watson-Watt was instrumental in the development of radar technology
throughout the war, and his work helped to shape the course of the conflict. He
also played a key role in the development of radar for civilian purposes after
the war, including air traffic control and weather forecasting.
After the war, Watson-Watt was knighted for his services to the country and
continued to work in the field of radio and electronics until his retirement in
1952. He died in 1973, but his legacy lives on in the continued use and
development of radar technology in both military and civilian applications.

AI Technical Trustability Update
While working on an update to my
RF Cafe Espresso Engineering Workbook project to add a couple calculators about
FM sidebands (available soon). The good news is that AI provided excellent VBA code
to generate a set of Bessel function
plots. The bad news is when I asked for a
table
showing at which modulation indices sidebands 0 (carrier) through 5 vanish,
none of the agents got it right. Some were really bad. The AI agents typically explain
their reason and method correctly, then go on to produces bad results. Even after
pointing out errors, subsequent results are still wrong. I do a lot of AI work
and see this often, even with subscribing to professional versions. I ultimately
generated the table myself. There is going to be a lot of inaccurate information
out there based on unverified AI queries, so beware.
