General Description

Claw is an RF inhibitor system that combines RF power electronics with a high gain Quintuple-Band antenna system designed to be mounted on suitable pan & tilt platforms. The inhibitor comprises two RF units covering the GNSS, 433 MHz, 915 MHz and 2.4 GHz and 5.8 GHz ISM and Wi-Fi frequencies with RF output powers to the antennas of up to 40 W. The antennas have a nominal gain of 15-17 dBiC producing an EIRP of over 300 W each for the 433 MHz and 915 MHz bands, over 1250 W for the 2.4 GHz band and 500 W for the 5.8 GHz band.
Each RF band can be individually controlled via the single control interface provided and Enterprise Control Systems Ltd (ECS) can support the development of custom RF inhibition solutions to defeat the operation of a range of UAVs.
Claw has been designed to defeat the RF datalinks of UAVs that are weaponised or that are being used for hostile airborne surveillance or other malicious activities. Claw can be integrated with detection,tracking and identification systems to provide the directional RF defeat capability to any Counter UAS platform in the Military or Critical infrastructure environment.
The Claw system is designed for maximum effective power output for minimum power input with the RF power electronics and antennas mounted on a suitable pan & tilt system on a mast or vehicle.
Claw is supplied with either mains AC or vehicle DC input power supply units that provide conditioned 72V DC output. The optional ECS positioner requires 24 - 48V DC input.

Software Defined Radio (SDR) Significant development investment in designing a bespoke Software Defined Inhibitor (SDR) for the complex signal source generation of C-UAS and C-RCIED inhibitors. The SDR is the system controller in Claw and is capable of generating two simultaneous wide band outputs Antenna Design High-gain, narrow beamwidth, antennas maximise the power density at the target threat device whilst minimising disruption of co-located systems In-house development allows bandwidth, polarisation and gain to be tailored to changes in threat devices identified in the field
