Battlefield Surveillance Radar

Battlefield Surveillance Radar

Kelvin Hughes SharpEye™ SxV X-Band Doppler radar is lightweight and quickly and easily deployed on a tripod, SMS (single mast solution) or vehicle for battlefield situational awareness.

The radar and control software can be used with any electro optic camera sensor and our innovative SMS (Single Mast Solution) which cleverly combines radar and electro optic camera sensors with slew to cue functionality on a single platform, providing discreet surveillance of an area.

With a SharpEye™ radar as the primary detection sensor, valley openings, open ground, tracks, junctions, tree lines and so on can be continually monitored, threats assessed and responses determined even in remote and difficult to access locations over long ranges. Battlefield surveillance radar solutions enables frequent and easy movement of location with a surveillance capability within a few minutes of arrival.

Complete single or multi node situational awareness 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 battlefield 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, dust and other forms of clutter. Due to their higher frequency Ku, K and Ka Bands are more susceptible to clutter.

SharpEye X-Band

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 RCS (Radar Cross Section) 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 snow, even sand storms.

Other differentiating technologies include MTD (Moving Target Detection) 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 and reducing the probability of detection by ESM equipment. Other Doppler radars may employ less advanced techniques such as MTI (Moving Target Indication) which does not take full advantage of the radial velocity information. Pulse compression is not possible for example with FMCW radars.

SharpEye™ SxV

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 as part of a multi node system or utilised as an independent mobile battlefield radar sensor positioned at frequently changing and possible remote positions, SharpEye™ SxV will provide all weather, day and night detection of areas of interest and maintain tracking of targets.

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™ Software

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.

CxEye Software

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.

Battlefield 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 surveillance operations 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.

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 battlefield surveillance and security requirements.

Communicating to a central C2 and or C4 can be achieved with microwave and or satellite communications links.
