Ground surveillance at low cost [DSEI17D2]

13 September 2017

Blighter Surveillance Systems (Stand S4-154) has introduced a new version of its B400 series Doppler ground surveillance radar.

The latest variant retains the capabilities of the existing B400 series, but has been re-engineered using innovative processing and control software to reduce its cost. The company claims it offers the lowest price per square kilometre of coverage of any ground radar, and a price that is also lower than CCTV and thermal imaging systems.

The Blighter B400 uses a passive electronically scanned array (PESA) antenna that scans small and slow-moving targets in cluttered environments. This is possible thanks to the radar’s coactive frequency-modulated continuous-wave (FMCW) Doppler fast-scan processing.

The antenna produces a wide beam that typically covers a 90° sector, and multiple units can be installed to increase coverage in increments of 90°.

The system is intended for critical infrastructure protection applications, and B400s are in use at several major international airports. The system can detect a human at a range of 4km.

Offering all the benefits of using an electronically scanned array, such as high performance, low manning levels, zero maintenance requirements and low false-alarm rates, the B400 is also supported by the company’s BlighterView HMI 2 software, which has been optimised for perimeter security. It can be used to control multiple sensors, including radars and electro-optical devices, with slew-to-cue capability for rapid detection and identification of intruders. The software can be used to create alert and exclusion zones.
