SPx Tracking Server – Radar Processing Software

Extract Radar Data and Track Targets

SPx Server is a COTS radar data extractor and target tracker for USVs that can be interfaced directly to vessel hardware or work with radar video sent over a network. The system processes polar format primary or IFF radar video to identify targets, correlating from scan to scan to provide positional and motion updates.

The system software includes the SPx Processing library, which provides a comprehensive range of radar processing capabilities, including:

• Gain control
• Area-based video removal (masking)
• CFAR thresholding
• Interference suppression
• and many other functions

User-defined processes may be incorporated into the processing workflow, allowing for custom solutions that use SPx as the integrating framework.

A variety of parameters can be configured to fine-tune the performance of the tracker, including:

• Minimum/maximum target speed
• Fixed or adaptive gain
• Expected target dynamics
• Measurement noise estimates
• Target size limitations

SPx Fusion Server – Sensor Data Fusion Software

Fuse multiple sensors into a single correlated data stream

SPx Fusion Server software fuses observations from multiple independent sensors into a single stream of correlated reports that can be broadcast over a network with no additional development required.

It can take in data from primary radar videos (using SPx Server) and also from secondary sources, such as AIS.

The SPx Fusion software allows users to assign a priority and a score to each sensor, giving more weight to sensors which are known to be more accurate.

Radar Data Integration

The radar software correlates the input source reports and generates a single set of output reports without duplicates. It can handle sensors that have an overlapping coverage region(s), e.g. an S-band and X-band radar, providing handover support as targets move from one sensor to the next.

HPx 346 – Radar Data Converter Hardware

Interface to a maritime or specialist radar

The HPx-346 is a small form factor interface and distribution unit that digitises analogue data from radars and distributes it as UDP packets over Ethernet. Available as an enclosed unit or as an OEM card for system integrators, the unit features a low-power ARM/FPGA-based System on Chip (SoC) that boots up in less than ten seconds and consumes less than 5W of peak power. So far we’ve interfaced to 80+ radars.  View all supported radars here

How does it work?

The unit accepts radar video, trigger and azimuth (ACP/ARP) signals as inputs, and can be configured to handle a wide range of signal types, including differential and single-ended with signals up to 60V, allowing it to interface with a wide range of different radar models.

The HPx-346 can be configured, controlled and monitored by a convenient and intuitive web interface, accessed via a standard web browser with no additional programming required.

HPx 450 – Radar Interface Card

Connect up to two analogue or digital radars

The HPx-450 is a versatile radar interface card that can operate in single- or dual-stream mode and can be connected to a wide range of analogue and digital radars for high-resolution data capture. Designed with an XMC Switched Mezzanine format, it is compatible with VME, VPX and Compact PCI processor cards, and features a four-lane PCI Express interface with data transfers of over 500 MB/sec.

The card supports a wide range of different radar signal types, including single-ended, differential, open-collector, and opto-isolated. Radar video, trigger and azimuth signals are accepted in the form of ACP/ARP or parallel data, and software alarms can be set for loss of triggers or azimuth data.

The flexible solution allows dual-stream functionality to be used in a number of different ways:

• Dual sampling of one radar video at different rates – for example, higher sampling at short ranges for maximum close-in detail, and additional lower sampling across the full radar range for maximum coverage
• Dual redundant mode – provides software-controlled automatic failover from one input channel to the other in case of loss of trigger, ACP or ARP signal
• Dual independent mode – simultaneous and independent capture of data from two separate radars

The HPx-450 is ideal for use in rugged embedded systems and is available in commercial and extended temperature variants.

Maritime Display Framework Visualization Software

Develop custom transponder & radar data user interfaces

The Maritime Display Framework is a software development package that allows users to create custom Windows .NET-based user interfaces for the display of primary maritime radar data and secondary transponder information.

Radar Data Visualization

The user interface can be customized to display scan-converted primary radar video, video track information, electronic charts, secondary transponder information, and camera video. Multiple camera windows with various input formats are supported, including H.264 via RTSP stream.

The software development package provides various tools for processing of information commonly required for maritime displays, such as generation of predictive vectors, calculation of a tracked object’s closest point of approach (CPA), and time to CPA (TCPA), providing warning of collision with other vessels. A comprehensive range of alarms can be built into displays, including target track alarm type and target dependence (such as hazardous cargo status provided in AIS).

VSD – Operator Display Software

Display and control integrated radar, camera & sensor systems

VSD from Cambridge Pixel is a customizable Windows-based platform that enables display, monitoring, and control of radar, camera, and sensor systems for security, surveillance, and counter-UAS operations.

Suitable for both fixed and mobile deployments, it supports hierarchical C2 and edge network configurations and can be operated effectively with minimal training. The software provides a cost-effective solution for developing advanced situational awareness across defense and security environments.

The system allows tailored 2D and 3D visualizations combining radar video, live camera feeds, panoramic views, and map overlays with real-time symbology. Multi-screen and multi-window layouts can be configured to suit operator workflows, while the platform supports both local and remote control of connected sensors and effectors. Integration with third-party tracking systems and AI-based classifier modules enhances detection accuracy and streamlines operational response.

Four Off-the-Shelf Variants

VSD is available in four standard configurations. VSD-Camera Standard provides multi-screen camera display with map-based slew-to-cue. VSD-Camera Advanced adds third-party tracking, AI classifiers, and sensor inputs such as AIS and ADS-B.

VSD-C2 Standard supports one C2 sensor or effector type, including radar or jammer control with alarm processing and MIL-STD-2525D symbology. VSD-C2 Advanced supports up to four C2 sensor or effector types with 3D and panoramic visualization. Cambridge Pixel also offers customization, branding, and extended interface support for specialized applications.
