Perimeter & CNI Protection Solutions
Kelvin Hughes provides radar based security solutions for the protection of Critical National Infrastructure (CNI). From nuclear power stations, gas processing plants and oil and gas installations to key government installations, SharpEye™ SxV radar deployed on a Kelvin Hughes Single Mast Solution (SMS) combining electro optic slew to cue cameras provides 360 degree surveillance of any perimeter.
A radar security solution from Kelvin Hughes can provide tracking of friendly and hostile targets several kilometres out from the perimeter, establishing an extended early warning perimeter.
With ever increasing threats to the security of CNI from individual persons, vehicles attempting to breach the physical perimeter or drones flown over the CNI area, radar based security can provide the time needed to determine a response.
A complete single or multi node situational awareness capability of a CNI facility can be developed through a Detect, Recognise, Identify and Classify methodology and the evolving picture controlled using the Kelvin Hughes control and interface software CxEye™.

SharpEye™ Solid State X-Band Pulse Doppler Radar
SharpEye™ radar technology meets the detection challenges of perimeter and CNI protection through a clever combination of radar techniques designed to provide the best performance in all conditions whilst also providing the flexibility to be optimised for specific detection needs.
Solid state radar ensures extremely high reliability. The radar can be deployed unmanned and the transceiver has no service or maintenance requirements.
Operating in the X-Band frequency differentiates SharpEye™ from most other ground surveillance radars as this frequency is significantly less affected by rain, sea, snow, sand and dust storms, and other forms of clutter. Due to their higher frequency Ku, K and Ka Bands are more susceptible to clutter.
SharpEye™ transmits a low power patented pulse sequence, which enables short, medium and long range radar returns to be detected simultaneously, allowing the radar operator to maintain situational awareness regardless of the range or zoom setting of the radar display software. X-Band pulse radar has other benefits too including an excellent long and short range capability unlike FMCW or microwave sensors which are typically limited to shorter ranges.
Doppler processing of radar returns provides coherent information concerning target velocity (radial) and enable the detection of very small and slow moving objects and targets with a low Radar Cross Section (RCS) and through a series of electronic filters is able to distinguish between the targets of interest and land and environmental clutter such as grass blowing in the wind and heavy rain or sand storms.
Other differentiating technologies include Moving Target Detection (MTD) providing enhanced clutter suppression at the Doppler processing stage and pulse compression of the return signal enabling a low transmit power providing efficient use of the radar. Other Doppler radars may employ less advanced techniques such as Moving Target Indication (MTI) which does not take full advantage of the radial velocity information. Pulse compression is not possible for example with FMCW radars.
A high performance, lightweight, mobile and deployable self-contained radar, weighing less than 20kg, SharpEye™ SxV radar will provide a cost effective and discreet airport security capability. Typically deployed on a single mast and with only one cable connection, installation is simple and reliable.
The radome enclosed unit consists of an antenna providing 360 degree coverage, a low power variant of the SharpEye™ solid state X-Band transceiver, GPS and it is environmentally sealed to IP67 to work in extreme cold, hot and wet conditions.
Whether the radar is being deployed as part of a multi node system on fixed towers and masts or utilised as a mobile radar sensor positioned at frequently changing and possible remote positions, SharpEye™ SxV will provide all weather, day and night detection of areas of interest.
The radar provides situational awareness information to the Kelvin Hughes radar control and display software CxEye™ and can easily be paired with electro optical camera sensors utilising the Kelvin Hughes SMS. CxEye™ also displays the camera information in the same picture as the radar.
CxEye™ - the Kelvin Hughes control and display software, integrates multiple sensors, such as radars and cameras, into a single, easy to use display package.
The software is a simple command and control system incorporating track fusion of multiple sensors, slew to cue of radar to camera, mapping functionality and a target priority tote, all presented on touch screen capable software. The software is extremely intuitive and requires little training.
Providing radar tracks, geo-referenced on a selection of mapping tools, the system can also fuse tracks from multiple radar heads into one user-friendly display.
Base security and perimeter protection can be achieved instantaneously, with reporting of threats achieved automatically or through user-determined parameters.
Radar tracks in different domains, displayed in an easy to understand format, will assist the user in evaluating and coordinating a response through a detect, recognise, identify and then classify methodology.
CxEye™ is capable of the seamless and automatic integration of a range of complementary sensors. Most commonly, electro-optical sensors can be paired with the radar using a slew-to-cue functionality.
Information from any additionally fitted sensors can be processed to give the operator real-time imagery and data to assist in picture compilation and threat assessment.
Passing of radar tracks and additional data is achieved through a range of communications options determined by the operational requirement. Multiple iterations of CxEye™ can be integrated to build a wider surveillance network with data and communications passed automatically to ensure a real time response capability.
Methods of Deployment
Kelvin Hughes will discuss with the customer how it wishes to conduct CNI and perimeter security and advise on the best methods of deployment of the radar and electro optic sensor selection. Kelvin Hughes is electro optic sensor and other sensor agnostic and is also impartial concerning the deployment method of the radar. The customer is free to source all of the core components separately or Kelvin Hughes can act as the primary supplier of the radar, camera and mounting method.
A common method of deployment includes SharpEye™ SxV radar and camera co-located on a single mast using the Kelvin Hughes through shaft SMS unit on a mast. This simplified approach enables the radar and cameras to be quickly and cost effectively deployed on a single mast with one cable connection giving 360 degree pan and tilt capability with no blind arcs.
Power and Communications
Kelvin Hughes can advise the customer on suitable power and communications systems required to provide situational awareness information to other locations and command centres. Depending on the application and customer requirements Kelvin Hughes can be the primary supplier or work with the customer and integrator:
- Military specification batteries for mobile and man portable applications.
- Solar panel, charge and battery system for mast mounted radar systems.
- Portable generators.
- Microwave and satellite communication links both portable and fixed depending on the deployment method.
