US Naval Air Warfare Center

Cambridge Pixel is supplying radar interface hardware and radar/IFF plot extraction software to the Naval Air Warfare Centre for the United States Navy's AN/SYY-1 Shipboard Air Traffic Control Processing and Display System. The new system will be deployed on all CVN-class aircraft carriers as well as on helicopter landing ships.

For IFF video, mode tags embedded in the video are used to identify the interrogation mode to permit correct decoding of altitude and identification code. For primary radar video, plots are identified as areas of video passing target-like acceptance criteria. Plots, along with digitised video, are passed out of SPx Server into downstream track processing and display.

SPx Camera Manager

A pan/tilt/zoom (PTZ) camera will often have a single control connection, either in the form of a serial port or TCP network connection. This makes it difficult for more than one client to control that camera. SPx Camera Manager makes the sole control connection to the camera and provides numerous client connections of its own, arbitrating commands.

The SPx Camera Manager application offers a simple, ready-made solution for projects that require a number of cameras to be shared by multiple display clients.

SPx Camera Manager can also act as a slew-to-cue server, supporting direct input of target track messages and steering the selected camera to follow that target.

Lidar Data

SPx Server now has built-in support for direct receipt of lidar data from market leaders Ouster and Velodyne. Data is received directly over Ethernet with no special interface hardware requirements, meaning that lidars can easily be added into the suite of sensors used on a project.

Lidar data is extremely high resolution and its potential applications include:

  • Collision avoidance and navigation on unmanned platforms
  • Traffic monitoring
  • Intruder detection
  • Crane collision avoidance
  • Railway crossing safety
  • Runway foreign object detection

Video Blending

The brand new video blending support within Cambridge Pixel's VSD (video security display) application allows any two video inputs to be mixed together into a combined video picture. Typically, blending is used to combine the video from a daylight camera with the video from a thermal camera, in order to highlight a feature of interest.

Controls are provided to configure the relationship between field of view and the required scaling and offsets needed to align the two videos correctly. Once configured the scaling and offset will automatically change as necessary, whenever the field of view is changed.
