Solid state, electronic scanning, long range ground surveillance radar
The Ranger® R20SS is a ground-surveillance radar specifically designed to detect and track personnel and vehicles within a 20 kilometer range.
With its electronic scanning capability and fast 2 Hz refresh rate, the Ranger R20SS has class leading target detection and acquisition performance.
The Ranger R20SS utilizes advanced tracking algorithms which enable fast detection and track initiation resulting in highly accurate target location with a low false alarm rate.
The system operates in the X-band for all weather operation and minimal effects from adverse weather and precipitation.
Fastest Electronic Scan Rate Available
The Ranger R20SS provides fast 90-degree, fixed sector coverage. Incorporating the next generation “track while scan” capabilities the entire 90-degree coverage area is covered twice per second.
When deployed on an optional pan/tilt device, the Ranger R20SS can provide 360-degree coverage.
Its low weight and easy implementation make it an ideal candidate for military vehicle applications and deployable in a man portable configuration.
As with the entire line of Ranger ground surveillance radars, the Ranger R20-SS provides high reliable system performance and 24/7 persistent surveillance, both within and beyond the fence.
Wide Area Surveillance for Desert Environments
The Ranger® R5 perimeter surveillance radar provides accurate, high resolution detection of vehicles and personnel.
This ground-based radar is designed to meet the rigors of a desert environment, providing 24/7 security to ranges of up to 5000m.
The Ranger R5 perimeter surveillance radar scans a full 360 degrees every second effectively monitoring up to 78 square kilometers (30 square miles).
Multiple units can be installed with overlapping coverage areas to protect larger areas such as borders.
As part of the FLIR integrated product suite, multiple units may be networked with any or all of the full range of FLIR radars and imagers to conform to terrain profiles and secure areas inside and outside a perimeter.
Using the radars’ advantage in detecting intruders, pan-tilt-zoom (PTZ) cameras can focus on their strength - identifying and assessing threats - for a more efficient and cost effective solution.

Blighter surveillance products address a broad range of security requirements in the defence, homeland security and civil/commercial markets.
Blighter radars are part of a range of advanced Plextek technologies that provide class-leading protection against both conventional and asymmetric/terrorist threats.
Blighter B400 series radars scan and detect moving vehicles and persons (including 'crawlers') over a wide area and provide exceptional range performance out to 32 km.
Detected targets are reported via wired or wireless TCP/IP network connections, allowing target recognition and identification through the automatic slew-to-cue of optional cameras or thermal imagers.
Accurate positional information is reported, including target lat/long co-ordinates, range and bearing.
The data bandwidth required for target output and radar control is very low.
The B400 series is Plextek's latest generation of e-scan ground surveillance radars (GSR).
E-scan radars have no moving parts to wear-out, maintain or replace and offer dramatic improvements in reliability.
Blighter radars are all-in-one fully integrated units comprising antennas, signal processing, plot extractor, GPS and compass.
Angular coverage is provided in modular units of 90°.
Blighter radars are proven to withstand harsh environmental conditions and provide many years of maintenance free operation.
The radar operates in all weather conditions and includes a built-in precipitation filter that suppresses false detections from rain or snow.
Day/night 24-hour operation is fully supported.
Low-power FMCW Doppler Technology
Blighter radars incorporate a unique combination of FMCW and Doppler processing technology, ensuring unsurpassed ground clutter cancellation with the ability to detect incredibly slow movement.
Radio transmission power is very low, making the radar safe for human operation and difficult to intercept (i.e. electronically covert).
Power consumption is low, allowing operation from battery, vehicle or mains.
Wide Elevation Beam
In order to maximize long-range detection performance, radars are typically mounted high on a tower or on top of a hill.
However, when mounted in this way, the narrow vertical elevation beam of traditional radars results in the problem of dead ground close to the radar.
Blighter radars benefit from having a very wide vertical elevation beam, allowing them to simultaneously detect targets in the distance as well as close-up.
In complex mountainous regions, the Blighter radars wide elevation beam also ensures that hill tops and valleys can be scanned simultaneously, without the need to physically tilt the radar.
Over flat land and calm water, the wide beam also provides rapid detection of low flying manned and unmanned aircraft including planes, helicopters, UAVs, microlights and hang gliders.
