I've got these in my collection, but it never hurts to go back over them.
Both these papers, of course, end their exploration of averaged correlation
by saying "and here a dynamic signal analyzer is typically used." :-P

It turns out that the common OCXO I was using has a higher PN floor than I
thought (about -154 dBc/Hz) so I'll probably switch to independent OCXOs
before delving into this too much further.
