This is the case.  US fighters since the F-111 have had rear-looking IR
sensors that look for hot gases (missile exhaust, jet-engine-airplane sneaking
up behind, etc).  The French deploy one such system as part of the launch
rail for their IR missile on the new Mirage 2000's: it looks like a prism
poking out a bit, with sensors inside it.
