Default Could this device be built?

I do not know if the tracking
radar and cop's radar gun were on the same band, however I do
know that 1MW of microwaves was sufficiently nondiscriminatory
at the receiving end to burn out its front end.


I bet it was sufficiently nondiscriminatory at the receiving end
to burn out the cop's front end, too.


When people talk about megawatt radars, they are talking pulse
peak powers. Radar pulses are very narrow - less than a
microsecond. However, its peak voltage that usually frys
semiconductors.


It is energy or power that fries the semiconductors more than
voltage per se.


If these megawatt-rated radars were not sending out short pulses,
but continuous power, they'd have to build a commerical electrical
generating plant next to them to run them in the field.


Nonsense, i have worked on projects with feeds in the 500 kVA to
5000 kVA range, they all were fed from the local utility at medium
voltage or 480/277 3-phase. They build generating plants at the
1000 MVA range (about 1000 times larger). This is excepting
co-generation where the idea is to make use of otherwise waste
gasses.
