Electronic Warfare Suite– The MiG-29 is the only aircraft in IAF after Dassault Rafale to have an internal
EW Suite. The D-29 EW suite of Mig-29 UPG is made by DRDO’s Defence avionics research establishment lab, Israeli Elisra, and Italian Electronica. The D-29 is a fifth-generation AESA based EW suite consisting of a Radar warning receiver, electronic support measure, and other electronic countermeasures. The ELT 568 Jamming system onboard are defensive in nature and are used to jam SAM’s and AAM’s launched towards aircraft, they are said to be effective on frequencies between 6-18 GHz by using an active phased array, further the EW Suite can alert of any digital frequency between 1-18 GHz. Jamming works on a cross-eye principle where artificially fake targets are created for the enemy to engage in them, such type of jamming is quite difficult to overcome. The D-29 consists of a Unified Receiver Exciter Processor (UREP modified to suit the requirements of D-29), Solid State Transmit / Receive Unit (SSTRU) with Active Array Unit (AAU), and a liquid cooling system. In simple terms, the D-29 EW suite in MiG-29 UPG works as a primary self-protection jammer and increases situational awareness by multiple folds.
