Looking for info for the AN/APS-31 used on the Skyraider

[skyrdredb]

Does anyone have any information on the AN/APS-31 radar used on the Skyraider? I saw a operation manual on the web a while ago but can not find it now. I am also looking for the dimensions of the nacell caried under the wing that housed this radar. I have the -N and -Q Skyraider flight manuals but they do not have much information on this system. Thanks for your help.

I don't know anything about it, but here's a photo I took of the tag of one at a wreck site. it reads:
CN-51A/APS-31 NOaS 51-500 AN P255 76 :CGG
