Israel Aerospace Industries (IAI) has introduced a new ComDart radio frequency geolocation system (ELK-7065VU), a 3D COMINT (Communications Intelligence or Communications Intelligence) for VHF and UHF. It is a solution that provides tactical forces with the geographic location of the opponent’s communication systems using an air platform such as a tactical UAV.
The system immediately detects communications transmissions over the VHF and UHF frequencies and provides an accurate geographic location of the radio frequency transmitters. With its ability to instantly detect transmissions both in open terrain and in dense urban areas, even push-to-talk (PTT) transmissions can be detected and precisely located with short pulses.
The heart of the ComDart solution is a compact vector antenna (Vector Sensor Antenna or VSA) from IAI’s ELTA department. This greatly improves the ability to pinpoint the location of the RF source. Previously, airborne COMINT technologies required multiple antennas and could only determine geographic location by capturing the intersection of multiple directional measurements generated by a moving aerial platform. This method takes time and processing power, especially when the emitters are moving on the ground. ComDart instantly and accurately calculates the 3D direction of RF emitters, so targets are instantly geolocated from a single platform.
The VSA antenna means a significant reduction in size, weight and performance (size, weight and performance or requirements on the SWaP type) so that no more than a small antenna is connected to a compact sensor unit (5 kg weight is required) . .) to have an instant functionality system that can be mounted on a UAV.
