Cambridge Pixel, a developer of sensor processing and display solutions, is supplying Plextek Ltd, the Cambridge design house, with radar tracking technology for its Blighter range of electronic-scanning ground surveillance radars.
The Blighter radar family - which includes the recently-launched Blighter B303 radar system - provides a solid-state, all-weather radar scanner that can operate over land and water to detect small moving targets such as people, kayaks or even low flying objects. Blighter radars are designed for mobile and fixed area, border and perimeter surveillance applications.
“We have successfully used Cambridge Pixel’s technology as part of a surveillance project to detect and track illegal immigrants trying to enter the USA across the hills on the Mexican Border,” said Nick Booth, Blighter sales and marketing manager at Plextek. “Using Cambridge Pixel’s tracking technology - we market this as BlighterTrack - operators are able to see the path travelled by intruders and at the same time filter out unwanted radar detections from wildlife and wind-blown vegetation so the targets presented are nearly always genuine targets and not distracting false alarms.”
The Cambridge Pixel tracking software receives radar detections from the Blighter radar and correlates information across multiple scans to create tracks that describe the position and dynamics of targets of interest. The tracks are then reported back into the BlighterView HMI display, or into a customer’s display or sensor fusion application.
The behaviour of the tracker may be defined using configuration files with the provision for different track processing behaviour in different geographical areas of the radar’s coverage. Multiple hypotheses are employed in its interpretation of the Blighter radar data to provide enhanced robustness and ability to handle a wide range of scenario types.
Plextek started developing the Blighter radar in 2003. Since then it has matured the technology and sold it into commercial, government and defence markets around the world. Today, the Blighter radar is protecting people and infrastructure in some of the toughest places in the world.
Commenting on this agreement, David Johnson, managing director, Cambridge Pixel, said: “The Blighter radar provides state-of-the-art capabilities for highly sensitive intruder detection and our flexible tracking software has been configured to exploit the sensor’s capabilities and to provide Blighter users with accurate target information while reducing nuisance alarms.”
Cambridge Pixel’s tracking technology is part of its SPx suite of software libraries and applications which provide flexible, ready-to-run software products or ‘modules-of-expertise’ for radar visualisation, radar video distribution, plot extraction and target tracking.
