Green Rock protects the force (ES14E5)

20 June 2014

IAI is showing its Green Rock mobile autonomous C-RAM (counter-rockets, artillery, mortars) radar in its operational configuration for the first time. The S-band radar was developed by the Elta division to provide warning against attack and a means of locating the firing source. The radar also has a capability against low-RCS and slow-flying airborne targets, such as UAVs, gliders and hovering platforms, and can perform friendly fire correction duties.

Designated ELM-2138M, Green Rock puts up a virtual radar ‘fence’. Any object that penetrates the fence is tracked and its ballistic trajectory computed. The threat is displayed on a screen such as a laptop. From the trajectory an impact point is calculated, allowing the operator to alert any forces under threat.

At the same time, the threat source location is calculated, enabling an immediate response by precision weapons.

Green Rock was developed to a contract from the Israeli ministry of defence and following successful trials is being delivered for operational use. The initial configuration comprises a single antenna array mounted on an all-terrain vehicle, as shown here at Eurosatory (Hall 6, Stand E738). A single array provides 90° coverage in azimuth and elevation. IAI has also schemed two-array configurations offering 180° azimuth coverage for fitment to vehicle or fixed platforms.
