Electronics

''Durjoy'' was equipped with one Pot Head radar for surface search. For ASW operations, she uses Chinese SJD-3 telescoping high frequency active sonar. Instead of being fixed to the hull, SJD-3 has a telescoping arm, so when not in use, the sonar is stored in the hull, and when deployed, the sonar is lowered into water several meter below the hull, thus increasing the detection range by avoiding buffeting generated by the hull.
