Multifunction Surveillance Radar Testing – HWDDC and the SPS-48E Meteorological and Aircraft Surveillance Capability
The HWDDC system is based on commercial off-the-shelf PC technology for the real-time radar processing and provides a web-service based operating interface and display for viewing radar imagery. Real-time radar imagery are provided via the ship's local area network (LAN) to various users onboard the ship, such as the meteorology and oceanography department, aircraft pilot ready rooms, primary flight operations, and the bridge. The production system configuration allows not only users onboard the ship to view data, but will also provide off-ship user access to the radar data over the Navy's secure network, providing data and imagery to forecasters and warfighters in a real-time manner.
The HWDDC processor performs several of the functions of a traditional weather radar processor, such as spectral moment estimation, but also contains specialized processing to extract accurate data from the tactical radar scan that is unlike traditional weather radars. The processor contains significant volume recombination processing to gather data from the rapid radar scans into a coherent data volume, adaptive sea-surface clutter filtering, and point target removal.
