It wasn't that far away from their Buccaneer design, AW.168.
The AW 169 had a miniaturised X Band AI Mk 18 derivative radar from GEC, with 33" antenna (radome had room for a 40" swept sphere volume). The Q band ranging radar was fitted in the starboard intake centrebody. Other equipment included X band, L band and S band "F.I.S. Mk 4" receivers (appears to be some kind of passive radar homing / RWR?) and Mark 10 IFF. Radar, FIS and IFF all displayed on the navigator's CRT display.
