Radar Solutions for BAE Systems Naval Program
New Royal Navy Ships get Cambridge Pixel Radar Solution
 

Type 45

Cambridge Pixel is pleased to be supplying

its SPx software-based Radar Scan Conversion and HPx-100 Radar Acquisition hardware to BAE Systems for deployment on the Type 45 Destroyer and QE Class Aircraft Carriers.

 

In a contract worth in excess of 600k, Cambridge Pixel will supply BAE with software and hardware components from its SPx product family. The solution will provide a video server to receive cmsthe ship's radar videos and compress them for distribution on an Ethernet network. At each client console,

Cambridge Pixel's software scan converter handles the display presentation of the radar video and supports the mixing with the application graphics. BAE Systems chose Cambridge Pixel's solution after a thorough assessment and comparison of available products.

New SPx Server Capabilities
SPx Server Handles Automatic Land Blanking

The latest release of SPx Server (V1.34) introduces some significant new developments. Among these is

server map

the support for automatic land area suppression for moving platforms. When used on a ship-based platform, radar returns from coastlines can cause problems for automatic track processing. SPx Server now provides a solution to this problem using a built-in World Vector Shoreline database at a resolution of 40 metres to support fully automated filtering of plots over land areas. A programmable threshold allows plots within a distance of the coast to be eliminated from consideration by the tracker. For a static platform installation, simply knowing the lat/long of the radar allows SPx Server to optionally suppress video and plots over land areas, significantly simplifying the set-up of the server. The new feature is standard in V1.34 of the Server and is available as an upgrade to all existing customers.

 

Radar Image Server - New Approach to Radar Display

 Radar Image Server

 

The new Radar Image Server (RIS) provides new options for cost-effective radar displays. The RIS runs as a server application that captures radar video from the usual sources and then scan converts to one ris2or more radar images. These images are then distributed in real-time to any number of client displays, including internet browsers. With the RIS, there are no client-side licenses for radar display, allowing for extremely cost-effective solutions where it is required to have many displays of the same radar video. The RIS can distribute up to 4 different views of the radar video, but each client is limited to displaying only what is available in those views.

 

In a typical application, the RIS distributes one full-range view of the radar coverage in addition to a number of zoom views of selected areas. A "CCTV" for radar can easily be created using a ready-to-run server and a web broswer application.

Tech Notes - From Recent Technical Support Issues

Pre-trigger Issues for Radar Video Interfacing

The radar trigger pulse defines a reference point for measuring the range of targets in the video signal. It is convenient to think of the trigger as defining range zero, but that is usually not the case. In many situations, there is an offset from the trigger pulse to the position of range zero. This is sometimes called the pre-trigger delay. If that delay is not considered, the radar video may be digitised and displayed but will not appear with the correct scaling on the screen relative to other graphics. In Cambridge Pixel's hardware cards and server software, the pre-trigger delay may be programmed, ideally by knowing the correct value from the radar manufacturer.
