There have been no details released afaik, so hard to tell.
It would be smart to stay close to either A-90B equipment (e.g. DSCN/Thales SUBTICS, which processes signals from the submarine's sensors, determines the tactical situation by track association, fusion, synthesis, trajectory plotting and management and handles all weapon command and control functions; Thales DR-3000U radar warning receiver, or Thales Underwater Systems - formerly Thomson Marconi Sonar - TSM 223 sonar suite, which includes bow-mounted sonar and towed sonar arrays, SAGEM periscopes and navigation system and Thales I-band navigation radar. Or what ever the S-20 boats will be delivered with (and that may include non-Chinese systems).
However, the P75I Scorpene Class also features the SUBTICS integrated combat system to enable operation and control of all onboard sensors, weaponry and radars from multifunction common consoles. The onboard S-CUBE integrated and modular submarine sonar suite, developed by Thales, offers increased safety against a wide variety of threats in deep or coastal waters. It comprises sonar arrays including bow, stern, planar flank, intercept, distributed, towed and active, mine and obstacle avoidance sonar, as well as self noise-monitoring hydrophones. The submarine is also equipped with Sagem surveillance and radars.
