Unless it's misquate,this article claim that type-1471 has max.detection range of 350km.let us put it this way CEASAR AESA radar for EF-2000 has max. detection range of 400km,while APG-77,at 380~390km range.
last year,there is a picture of two J-11B ,each with different nose, which mean PLAAF may be testing new gen. FCR radar to replace the slotted array antenna.
instead of a all new radar to to minimized risk,more likely that radar incoporate some modification,replacing the mechanical slotted antenna with PESA or AESA antenna.similiar to USAF APG-64V-5 AESA
