C400 SERIES COASTAL SECURITY RADARS

► Coastal security radars suited to fixed, mobile and portable applications

► Optimised for detection of small and slow moving boats

► Modular scanning: 90°, 180° or 360° (2x 180°)

► Fully electronic scanning (e-scan) using PESA and FMCW technologies for ultra-high reliability

► Unique sea clutter filter (SCF) for low false alarm rate

► Choice of radar configurations: low-cost, short-range system or high-performance, long-range system

► Enhanced environmental protection (marinised)

► Static target detector

Blighter C400 series coastal security radars build upon the heritage of the Blighter B400 series ground surveillance radars (GSR). C400 series radars have a modular, non-rotating, entirely solid-state design.

Blighter C400 series coastal security radars build upon the heritage of the Blighter B400 series ground surveillance radars (GSR). C400 series radars have a modular, non-rotating, entirely solid-state design. The radar’s electronic-scanning (e-scan) system is implemented using low-power passive electronically scanned array (PESA) and frequency-modulated continuous-wave (FMCW) technologies. This ensures industry leading levels of reliability with minimal in-situ maintenance.

Blighter C400 series radars are designed for coastal security applications including seaport security surveillance and water-side security of land based coastal assets, such as oil and gas installations, desalination plants, nuclear power stations, palaces and other high value assets. Additionally they can be used for river and estuary monitoring in situations where traditional bulky coastal surveillance radars are unsuitable.

Coastal Security Radars with Doppler Processing

Blighter C400 series coastal security radars use advanced Doppler signal processing to provide the ability to precisely examine the motion of waterborne objects with respect to waves or ripples on the water surface. This allows the radar to separate targets of interest from the background water clutter so that it can detect very small targets even in cluttered environments. For example this allows an intruding kayak, RIB (rigid inflatable boat) or other small boat to be detected alongside larger ships or in ports.

Detection of Static Targets

Unlike traditional Doppler radars, Blighter is able to characterise non-moving targets so that moored boats, buoys and other structures remain visible on the radar screen. The radar’s built-in sea clutter filter (SCF) automatically adapts to changing sea states and wave conditions

Blighter C400 series coastal security radars can be used as part of a larger coastal security system including day/night and fog penetrating electro-optical camera systems, AIS (Automatic Identification System), other boat tracking systems and CCTV with control and display through the BlighterView HMI C2 (Command and Control) software application.
