SharpEye™ radar technology meets the detection challenges of national border security and border surveillance 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.
Single Mast SharpEye
Doppler processing of radar returns provides coherent information concerning target velocity (radial) and enables the detection of very small and slow moving objects and targets with a low Radar Cross Section (RCS). Through a series of electronic filters SharpEye™ is able to distinguish between the targets of interest, land and environmental clutter such as grass blowing in the wind and heavy rain or sand storms.
SharpEye™ Long Range X-Band transmitters are the first in their class to employ Gallium Nitride (GaN) power transistor technology. The significant performance benefits of GaN transistors have been harnessed to directly improve the performance of the radar.
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 the efficient use of the radar and reducing the probability of detection by ESM equipment. 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 can be transported by personnel on foot, vehicle or deployed on a single mast. 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 along a border 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 along a national border, SharpEye™ SxV will provide all weather, day and night detection of areas of interest either up to the border, beyond the border line while maintaining tracking of targets that cross into the country.
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.
SharpEye™ Long Range
The SharpEye™ Long Range solid state high performance X-Band radar is designed for easy installation on a choice of platforms, with either a fixed or telescopic mast system or installation on fixed infrastructure, providing long range surveillance for open areas, remote borders and unmarked national borders.
Deployable as a single surveillance unit or part of a multi node radar system SharpEye™ Long Range will operate continuously in all weather conditions day and night and can be operated autonomously under remote supervision. The unit is rated to IP67 to work in extreme weather and temperature conditions including high winds, heavy rain, snow and high and low temperatures.
Designed to be elevated high up to provide long range national border surveillance and situational awareness, the system comprises a self-contained turning unit which also houses the SharpEye™ X-Band radar transciever, and a 5.5m low profile antenna to provide 360 degree coverage.
By including the SharpEye™ radar transceiver in the turning unit housing, waveguide is not needed to be routed down the elevating structure such as a scissor lift platform. With the radar processing carried out in the transceiver there is no signal degradation. A simple single cable loom is used to connect to the radar.
Various systems can be used to deploy the radar from lattice towers and trailer based scissor lifts to ISO containers for both remote and manned operation.
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. 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.
Border surveillance 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 border surveillance 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 SMS unit and a pneumatic telescopic mast. The advantage of this approach is that the radar and cameras can be deployed quickly on a single mast with one cable connection giving 360 degree pan and tilt capability with no blind arcs. The mast can be supported on a tripod, integrated into a trailer solution or integrated into a vehicle.
A Mil-Spec portable tripod mount is available for man portable deployment where the SharpEye™ SxV sensor is mounted directly onto the tripod. Power and Ethernet connections come from a single loom and are connected to a ruggedised laptop running the CxEye™ radar control software. A camera suited for battlefield conditions can also be connected into the CxEye™ software.
SharpEye™ SxV can also be directly mounted to a vehicle. For SharpEye™ Long Range radar deployment, a number of options are possible depending on the Customer’s border surveillance and security requirements.
ISO container solutions with a telescopic platform or scissor lift provide a complete surveillance suite of SharpEye™ Long range radar and electro optic cameras. The ISO container solution can be manned and include power, air conditioning, water etc. or unmmanned with remote autonomous control providing permanent surveillance nodes along a border and communicating back to a central C2 and or C4 via microwave and satellite communications links.
Trailer systems for semi-permanent deployment are also possible, where the platform is configured with a scissor lift for deploying the radar, generator and a small air conditioned surveillance cubicle for on site manning. Communicating to a central C2 and or C4 is achieved with microwave and or satellite communications links.
