Some Listers might still think that a megawatt sounds like a lot
of power. But it's worth remembering the steps involved in
between the transmitter stage and the arrival of the radar beam
on target. (Excuse the gross approximations that follow, but
they make the general point.)

If the peak power of a radar is a megawatt (typical of modern
ATC and TMA radars) this is the power reached at the peak of
each pulse, but each pulse lasts only in the order of a
millionth of a second. In order for the _average_ maintained
power to be approaching one megawatt there would obviously have
to be a million pulses per second. But there will only be in the
order of a thousand. So straight away you can see that the
average output power in the beam is in the order of kilowatts -
 a kW being about equal to the consumption of one bar of an old
electric fire.

But that's not all. This kW of radiated power is spread through
a huge volume of space, typically in these surveillance radars a
wedge a couple of degrees wide and maybe 30 degrees tall. The
equivalent area covered by that solid angle at range (say) 10
miles is about 1/5 of a square mile, so the average energy
density is clearly pretty tenuous. An object (say) 30ft in
diameter will intercept about 1/30,000th of that total energy
per unit time, so in other words the average power on-target is
in the order of 1/10 of a one Watt.

How can this be right? That tiny power then has to be reflected
from the target miles through the atmosphere and received back
at the radar. Yet radar can not only detect tiny things like
birds, insects and hailstones at incredible distances but
measures their distance from the radar to within millimetres
hundreds of times a second. Doesn't sound possible, yet it is
done every day with received powers in the order of one micro-
microwatt (10^-12Watt).

It's truly a miracle that radar works at all, the power levels
are so low. And talk of damage caused by "high power" radar
needs to be taken with a pinch of salt.

Another point is that most radars only illuminate a given target
for a fraction of a second once every antenna rotation, so we
could take off another order of magnitude from the average power
on target. But this is not the case for tracking radars, of
course, where the antenna stays on the target. And also these
radars have pencil beams, so the output energy is concentrated
in a smaller solid angle. On the other hand these tend to be
smaller, mobile dishes with lower peak powers and also need
excellent range accuracy which implies short pulse lengths. One
the whole similar arguments apply: The average energy on target
is small, and is not going to fry the circuitry or cook the
aliens.

Interfering with control systems is of course a different matter
that need have nothing whatever to do with power and is about
unwanted information in the signal. I suppose the suggestion is
that saucers are so confused by detecting simple, regular pulses
of radio energy that their autopilot-analogues don't know which
way is up any more and crash. But I find this hard to credit.
The EM spectrum is full of all kinds of broadcast radio
information from many sources, of which radar is only one, and
even in 1947 surely there were commercial and military radio and
radar sources all over a country like the US. Isn't it a bit odd
that they would crash in just those remote desert places where
EM pollution is probably at a minimum, rather than around big-
city areas where there might be a howling confusion of radio
noise, night and day?
