Hello,
I am a grad student in CS doing underwater networking design. I was
designing what I thought was a novel algorithm for detecting self
reflecting echoes to tones sent by our modem as wakeup calls to the
network.
As it so often happens I was recently reminded by someone that an
obvious predecessor to my work would be radar/sonar which identify
targets based on echoes sent (in active measures). The one thing I
want to do differently is not to identify targets, but the static echo
locations from surfaces. Now I understand that in order to identify
the target, something must be done in radar processing to IGNORE these
surface reflections. My quick read on radar/sonar on wikipedia didnt
show how these non-target based echoes are differentiated from your
moving targets.
I understand that work on sonar also has simply ranging information
where ALL surfaces can be displayed based on their receive times, but
I want to do something different: i.e. I want to identify only those
echoes that occur repeatedly at the *same* time due to static
surfaces. Can some one please tell me what algorithms are used for
this purpose.
Thank you.
Affan.
