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.
