DATA SHEET
SPx Server is a multi-function radar processor that, with different
SPx-Server license options, can provide the capabilities of a radar distribution
server, plot extractor and target tracker.
Receiving radar video from a sensor either through the HPx family or direct
from a network, SPx Server provides a set of configurable processing
modules that permit the incoming video to be processed prior to
distribution and analysis.
Video Distribution with SPx Server
When used as a distribution server, SPx Server compresses the video and
delivers the data to client consoles across standard Ethernet networks.
Distribution is based on UDP multicast, ensuring that the network
bandwidth is a function only of the radar signal and is independent of the
number of client consoles. Each client display receives the same polar-
format radar video and can create its own independently-controlled scan
converted radar image (for example using the SPx scan converter software).
Target Extraction and Tracking
The Plot Extraction module examines the processed video to identify
target-like radar returns. A set of configurable parameters define the target
size of interest, allowing small noise returns or larger clutter or land
masses to be eliminated early in the processing. An adaptive CFAR
threshold is used to separate likely target returns from background noise.
Features:
Plots may be eliminated for further consideration by using an area mask.

Configuration and Control
A Graphical User Interface is provided for server configuration and
maintenance. This provides a full set of tools to visualise the video, plots
and tracks. Once configured, the server may be started as a background
process and controlled through a network interface.
