INS "Tabar"s sonar is the BEL APSOH (Advanced Panoramic Sonar Hull) hull-mounted sonar. The APSOH sonar has active ranging, passive listening, and auto tracking of targets. For countermeasures INS "Tabar" includes chaff and infra-red decoy rounds fired by four KT-216 launchers. This ship was originally equipped with the Russian TK-25E-5 electronic warfare suite and was later replaced by the BEL manufactured Varuna ESM/Electronic warfare suite with its distinctive circular housing located above the Fregat radar.
