A little of uncle Google might help.
Description: The Russian Richag-AV is a groundbreaking radar and sonar jamming system developed by KRET and designed for integration on rotary-wing aircraft, ships and other military platforms such as airplanes and ground vehicles. This new system is the successor of the Smalta jamming system developed in the 1970s with an effective range of 100 kilometers. The Richag-AV is able to jam advanced sensor systems from distances of several hundred kilometers away. The jamming capabilities also may include other detection systems with the aim of defending aircraft, helicopter, drones, ground and naval forces. The system utilizes multi-beam antenna arrays with�DRFM (Digital Radio Frequency Memory) technology jamming any radiofrequency based weapon system. Richag-AV can be employed to carry out radar-based intelligence gathering finding foreign sources of electromagnetic radiation. An onboard database allows to quickly determine the type of targeted radar finding the most effective way of jamming. According to KRET the Richag-AV has no equivalent in the world. KRET delivered the first batch of three Mi-8MTPR1 helicopter-mounted Richag-AV to the Russian Armed Forces on March 4, 2015. The Russian Armed Forces will take delivery of 18 Mi-8MTPR1 systems by October 2016.
