Radar Ambiguity Function - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

I read in an IEEE paper that "the noise-like characteristics of FM radio signals have an ambiguity function that approaches the idealised thumb-tack surface". My question is: Why do random (noise-like) signals approach the idealised thumb-tack ambiguity response? I'd have thought that since the signal is random, thus unpredictable and ambiguous, that the ambiguity spike would have been distributed broadly over the surface (i.e. the opposite of the idealised thumb-tack response). Any light on this would be appreciated.
