I make no promises of success where Sicily is concerned but there is radar material in:

AIR24/3461: MAAF (Int) FIU Signals Reports Nos. 3 to 26 (4 missing)
AIR24/953: Intelligence Summaries, Mediterranean Photographic Intelligence Centre (Aug–Oct 1944)
AIR24/954: Intelligence Summaries, Mediterranean Photographic Intelligence Centre (Aug–Nov 1944)

Also, a search of series AIR51 under "HUSKY" will give you a long list of possibilities.

There is also intelligence material in AIR51/296 which may help you.
