Radar technology provides many tactical advantages during warfare, but it can also serve well in civilian applications, including for border security and surveillance. The patented SharpEye radar technology from Kelvin Hughes has been used to detect and track ground-based and aerial targets in difficult-to-access locations such as border crossings between countries.

The solid-state radar system employs pulse-compressed Doppler radar techniques at X-band frequencies. It requires no maintenance or service and is less affected by environmental and weather factors such as rain and snow than higher-frequency surveillance radar systems.

One version of the system, the SharpEye SxV, is a mobile, lightweight self-contained unit that weighs around 20 kg and can be readily transported to different locations for deployment on a mast or tripod. The radar is able to be deployed along a border as part of a multi-node system or deployed as a mobile-vehicle-mounted surveillance package.

A more permanent version of the system, the SharpEye Long Range system, features co-located radar and electro-optical subsystems. With simple setup, it delivers 360-deg. radar and camera surveillance. The system uses gallium-nitride (GaN) amplification, with its transceiver contained in the antenna turning mechanism. It employs a 5.5-m, open-array, low-profile antenna configuration.

Jonathan Field, Kelvin Hughes’ director of security systems, says, “The increase in demand that we are seeing for our border-control and surveillance radar applications is a reflection of the many benefits our SharpEye radar technology can deliver—high performance, high reliability, easy deployment, versatility, and significantly reduced through-life costs.”
