The Blighter B202 Mk 2 man portable radar scans and detects moving vehicles and persons (including ‘crawlers’) over a wide area and provides exceptional detection performance out to 8 km.

Detected targets are reported via a standard Ethernet TCP/IP network connection, allowing target recognition and identification through the automatic slew-to-cue of optional cameras or thermal imagers (see Blighter Explorer). 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.

Electronic-scanning (E-Scan)

The Blighter B202 Mk 2 is BSS’s low cost e-scan ground surveillance radar (GSR). Blighter e-scan radars have no moving parts to wear out, maintain or replace and offer dramatic improvements in reliability over mechanically scanned radars. Blighter radars are all-in-one fully integrated units comprising antennas, signal processing, plot extractor, GPS and compass. 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.

Man Portable Radar with Wide Elevation Beam

In order to maximise 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 detect targets in the distance as well as close-up simultaneously. In complex mountainous regions, the Blighter radar’s wide elevation beam also ensures that hill tops and valleys can be scanned simultaneously, without the need to physically tilt the radar.
