DARE had developed the Trap, Trumpet, Tempest, Tusker Pod based jammers which are in use with IAF Mig-27s. They are primarily noise jammers coupled with the Tarang RWR. Being noise jammers they had serious limitations with respect to power consumption, vulnerability to enemy detection, effectiveness against frequency hopping emitters.
The Elta EL/L-8222 Airborne Self Protection Jammer (ASPJ) pods are a standard fit on the SU-30MKI, Jaguar, Mig-21, Mig-27 with the LCA also tested with it. It operates on the Digital Radio Frequency Memory (DRFM) principle where it receives, detects, classifies the signal waveforms, stores them, adds a delay and sends it back to the adversary emitter to be picked up, thereby giving incorrect range data and even azimuth if the scan patterns are known. In comparison with noise jammers they have lower power consumption and are difficult to detect and counter. DRFM jammers severely degrade adversary radars and missile seekers.
At Aero India 2017 Alpha Design had showcased upgraded packages for the Elta EL/L-8222 ASPJ to convert them to wide band EL/L-8222WB pods in cooperation with IAI. This upgrade will allow them to counter a wider variety of radio frequency threats.
DARE at Aero India had also indicated that it had developed a High Band Jammer (HBJ) pod for SU-30MKI aircraft to be carried at the wingtips. The new indigenous pod is expected to have better integration with the RWR on board than the existing Russian SAP-518 pods.
