Recomb and despoke

(OP)
I'm having trouble finding out what these terms mean in the context of spatial spectrum estimation and broad band beamformers.  I haven't been able to turn up any material on either, any ideas?

Hell, I thought you made 'em up.

What were you reading before the medicine kicked in?

RE: Recomb and despoke

Amusingly, a 'tight' Google search, looking for both terms) finds ONLY your question (this one, right here, now).

That's us on Google. Look up and wave to the passing Google Spider-bot. wavey2  

 

RE: Recomb and despoke

Just a couple of guesses -

A comb generator is typically a pulse source, with the comb defined by the harmonics of the pulse repetition rate.  A very narrow pulse that repeats every 10nS will have fairly level 100 MHz harmonics out into 10s of GHz.  Recomb could mean to change the base frequency (repetition rate) of a pulse to shift the harmonics (the comb) to other frequencies.  I suspect you would have to frequency lock to the pulse and then generate a new pulse at an offset frequency.  

Despoke - Potentially bandpass a harmonic to make a hole in the comb.  Not an easy thing to do but you can knock the harmonic down by a few/several decibels.
