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.
