Coastal Surveillance and Maritime Security


Coastal surveillance and maritime security systems require the integration and presentation of information from many different sources, including primary radar, AIS and CCTV. SPx software provides high-performance software components for system integrators to build integrated radar and video display solutions. With its "modules of expertise" approach, the SPx software simplifies the addition of radar and camera display into new or existing applications.

Radar Interfacing

Radar interfacing is a core requirement for many coastal surveillance and maritime security projects. Radars can provide the long range detection capability that is often needed.


Cambridge Pixel has extensive experience interfacing to many different makes and types of radars. The HPx series of radar interface cards can be used with radars that provide analogue signals.

For modern radars that provide a Ethernet data output instead, the SPx software has direct support for numerous data formats including ASTERIX CAT-240 and several proprietary formats from manufacturers such as Terma, Simrad, Raytheon and Wartsila.

Target Tracking

Cambridge Pixel's established SPx Server application provides automatic, multi-hypothesis, model-based target tracking from a radar video input.

Track messages derived from the radar video data are output onto the network for client applications, such as RadarWatch, to receive and display.

Camera Integration

Cameras form a crucial part of many surveillance and security projects, providing operators with visual awareness potentially out to several kilometres. A number of Cambridge Pixel's ready-made display applications include the ability to display video from multiple cameras. Steerable cameras may also be locked onto a designated target and continuously steered to point at it.

RadarWatch also features the ability to overlay radar and AIS track information on the camera video, easing the operational load on operators.

Transponder Data

Transponder-based data such as AIS and ADS-B can form part of an integrated sureveillance picture. Many of Cambridge Pixel's applications provide support for receipt of AIS and ADS-B data.

Transponder data may be fused (correlated) with primary radar track data, enhancing situational awareness. Comparing primary radar tracks to AIS is also a very good way of identifying potential threat targets, which will generally not be using cooperative transponders.

Alarm Logic

A common requirement in maritime security projects, regardless of sector, is the ability to monitor defined geographic areas, alerting the obsever to intruders or potential intruders.

RadarWatch features highly-configurable and flexible alarm capabilities. Operators may be alerted to boundary-crossings, proximity violations, area incursions and potential collisions. A "safe-list" allows known, trustworthy targets (e.g. maintenance vessels) to be exempted from raising alarms, further reducing the operator load.

Offshore Oil and Gas

Cambridge Pixel's products are already deployed around the world, by a number of different offshore oil and gas customers, providing radar tracking and display solutions.

Uniquely in this sector, Cambridge Pixel's solutions can take into account the motion of the platform itself, providing for enhanced tracking accuracy.

Critical Infrastructure and High-value Assets

Any high-value asset is obviously worth protecting and the sooner a threat is detected and confirmed the sooner it can be neutralised or mitigated. Bringing together a range of sensors is the best way to protect against the multitude of threats that exist in the marine environment.

Examples of installations that may benefit from a modern security/surveillance solution include:

  • Bridges, dams and locks
  • Wind farms
  • Offshore oil rigs, gas platforms and other deep sea operations
  • Deslination plants, waterside facilities and nuclear power stations
  • Navy, marine corps and coastguard bases
  • Fish farms
  • Permanent marine hazards (wrecks, sand banks, submarine cables etc.)
  • Marine conservations areas
  • Military firing ranges

The SPx software supports the capture of radar video from major radar manufacturers including Kelvin Hughes, Terma, Navico (Simrad), Raytheon, Sperry, JRC and Furuno. An HPx radar input card may be used to interface to analogue radar video, trigger and turning data or, where network radar video is available (for example in ASTERIX format), this can often be input directly into the SPx software framework.

The capabilities of the SPx software are available to system developers in the form of software libraries and complete ready-to-run applications. In a typical system, the SPx Server application provides tracking from radar video and those tracks may then may be output into the client application and may be fused with AIS data by the SPx Fusion Server software. The client application may be one of Cambridge Pixel's ready-made display applications, such as RadarWatch, or it could be a custom application written using the SPx library to provide core radar display capabilities.

Cambridge Pixel's turnkey display applications offer a fast, cost-effective solution to receipt and display of sensor data, supporting: multiple radar videos, with underlay maps or electronic charts, AIS/ADS-B targets, radar tracks and video from multiple camera sources. Camera steering control (including slew-to-cue) is also supported by a number of display applications including RadarWatch, VSD and RadarView.

Cambridge Pixel's software modules are already being used in numerous diverse coastal surveillance and maritime security projects worldwide, from protection of offshore oil and gas facilities, to monitoring safety zones at firing ranges, to helping to keep bathers safe on beaches.

Some examples of where Cambridge Pixel's products can be used are outlined below:

  • Asset Protection

    Protection of high value waterside and offshore assets, such as oil rigs, nuclear power stations and industrial facilities.
  • Critical Infrastructure

    Monitoring of critical infrastructure, such as bridges, dams and wind farms.
  • Safety Solutions

    Within maritime collision avoidance systems and safety solutions around designated marine hazards or military danger zones.
  • Border Protection, Search & Rescue

    Border protection and search & rescue operations, detecting and locating small targets.
  • Traffic Monitoring

    Observation and monitoring of vessel traffic in waterways, rivers, estuaries, small ports and harbours.
