My only concern is that the Aerosonde UAVs will be over hyped to the
point
people will get the wrong impression of what they are and what they are
capable of.

Yair. Well.

Not helped by the hype on the Aerosonde web site rabbiting on about its
radar disruptive capabilities - shortly after saying the total power
available is 30 watts or similar. It's not my field but I have a
severe
problem believing 30 W in a UAV will disable your average
anti-aircraft/G-A
missile radar......

30 watts RMS is more than enought to disrupt most airborne radars.
remember the radar duty cycles are very very short, typically less
then .1%, so the ERP from 30 watts rms could easily be in the tens of
kilowatts.

Ground based fire control radars are another story. Those things
often have ERP's of several hundred megawatts. They are designed to
burn through almost any kind of intereference.


Erm... I DID say..:-
"I have a severe

Are you suggesting anti-aircraft/G-A missile radars are airborne?

Or do you think they might be "Ground based fire control radars" which
"are another story"?

Depends whose it is. The Russian and American Fire Control radars are
awesome beasts, however as you move to more locally manufactured
product, they start to look more and more like the capabilities of
airborne radars.

AFCS - what sort of a cop out is that? Are you suggesting the Solomons
have a home groan radar industry?
You never know who has been trading what with who. You can often be
surprised at how good indigenous engineering is as well. NEVER
UNDERESTIMATE the resources or persistence of a highly motivated
enemy.

If you asked someone what the odds were that an F117 could be shot
down by a soviet SAM 5 years ago, everyone would have laughed at you,
but a combination of smart indigenous engineering in Kosovo, and a
dumb USAF resulted in just that.

The US did indeed try fitting an airborne radar onto a AA gun, it was
called the Divad. It was a spectacular failure, and was cancelled long
before it ever got into volume production.

The really good Russian and US stuff is hard to get on the black
market, the not quite so sophisticated Indian, Chinese, French, North
Korean stuff is a whole lot easier (and cheaper) to get, and a whole
lot less capable.
