IAI Reveals New Passive Coherent Location System

ELTA Systems, Israel Aerospace Industries (IAI) Group and subsidiary, recently unveiled its new Passive Coherent Location System (PCL). The system enables the creation of an air situation picture that tracks non-emitting targets using non-cooperative transmitters. It detects and tracks aerial threats based on target reflection from non-cooperative transmissions from FM or Digital Audio Broadcasting (DAB) towers. The reflections are received by one or a network of antennas, providing 3D real-time omnidirectional coverage for tracking of multiple targets in congested airborne traffic.

The PCL system is simple to deploy and can be located on remote borders, as well as in urban areas. With 360-degree coverage, installation can include one sensor or a cluster of sensors for redundancy and improved coverage of specific problematic areas. The sites are connected to the central PCL command and control processing unit via a dedicated data link.

The new system is already deployable and provides real-time aerial mapping, of non-emitting threats.

Multi-disciplinary Picture

VP and General Manager of IAI’s ELTA Intelligence, Communications and EW division, Adi Dulberg, said: “We are proud to introduce the new PCL system developed by IAI/ELTA, that detects and classifies aerial risks without unveiling the locator. The PCL system creates air situation picture and can be deployed independently or as an additional layer for air control radars, as part of a multi-disciplinary air situation picture”.

Dulberg explained that PCL is a solution that enables systems to passively target aerial targets even if they don’t radiate by using civilian radio stations (both FM and digital broadcasting) that transmit and hit the aircraft.

He was further quoted saying that the system would be of interest to every country in the world because everyone wants to know what’s going on in the sky, be it civilian or military aircraft and unmanned aerial vehicles.

The PCL System (ELK-7080) receives reflections by one or a network of antennas, providing 3D real-time omnidirectional coverage and enabling accurate detection and tracking of multiple targets in congested airborne traffic. The PCL does not transmit, thereby not exposing its location.

Some of its key features include that it can covertly detect and track aerial targets and exploits analogue FM broadcasting and DAB for non-cooperative aerial targets detection. Moreover, it can simultaneously process multiple FM and DAB broadcasts and is immune to jamming.
