Elbit unveils miniature reactive jammer for vehicles protection

Elisra, a unit of Elbit Systems, has introduced a Miniature Reactive Jammer (MRJ), an electronic warfare system designed to jam remote controlled improvised explosive devices (RC-IEDs) activated against armoured and VIP vehicles.

Capable of operating in high frequency ranges, the MRJ system is used for a range of missions dealing with continuous border security, personal security, incursions into hostile areas and protection of vehicle convoys.

Elisra general manager Edgar Maimon said that company has developed the MRJ system leveraging on operational experience in building self-protection jamming systems for various platforms.

"The new system is a breakthrough in the field of jamming RC-IEDs activated against military and VIP vehicles due to its ability to effectively counter modern threats, while saving energy and minimizing the risks in detection, as opposed to previous systems," Maimon added.

Additionally, the MRJ reactive system can analyse intercepted signals and jams potential threats by concentrating the jamming energy on a particular frequency range or on a specific frequency, more efficiently and cost-effectively.

Suitable for protection of any vehicular platform, the new system meets the requirements of Size, Weight and Power (SWAP) and will be deployed with Jammers already in operational use by the Israeli Defense Force and other customers to enhance capability.

The lightweight and modular system allows users to select frequency ranges for each operation (ranges of 25 – 6000MHz), covering every threat in the frequency range.
