This is a point I've wondered about: it seems that vessels with active

radar

appear on my radar with a large arc centered on the vessel's blip. I've

assumed

this is an interaction between their radar and mine. Does this also mean

that

my radar also enhances my picture on their screen?


This may also be due to having the gain/intensity, turned up too high
for the given range scale you are using. It can sometimes be countered
with the anti clutter controls, alone.



Who said I wanted to get rid of it? Its kind of nice have a special identifier
for some vessels. How can I enhance it?

Problem is, what I feel you are describing, may not be due to
interference from another radar.
In the past, when I experienced interference, it showed more as a spoke
coming towards me, or a series of dots, behind the target (it tends to vary.
What you are are describing, sounds more like "side lobe" effect, in
which case it's not something you'd want to enhance .... course, I could
be miss reading/understanding your description.

Also, to a lesser extent, you become visible to other shipping in a
way that a horn can't: precisely.

Don't count on it. The arc that you see from the other guys radar is
from interference from his transmitter. Your radar is picking up your
transmitters echo and his transmitter directly. His pulses are not
synchronized with yours so you see the trail of pulses from his
transmitter while your transmitter is between pulses. It will give
neither of you any indication of where the other is.

This only happens if the two transmitters are very close to the same
frequency. Even though the two radar's may be exactly the same type of
radar, they may or may not be close enough to the same frequency. The
magnetrons are all tuned slightly different and drift somewhat.

On most radar's there is also an interference filter on the receivers
that eliminate or reduce that type of interference.

Then too the other ship may be using a radar in a completely different
band. No interference to either of you.

Gary

My understanding is that this is reliant on the radar band in which
they are operating their active radar, and/or whether they have a
receiver that goes ping (or whatever) when glanced by "yachtie" radar.

That's why, my little trollsmeg, I said "my understanding". Perhaps
you would enjoy taking the lid off that planet-sized intellect to
share your god-like insights with this NG?

Or just shut the **** up.
