Automatically detects and characterizes pulse and Pulse Doppler signal energy
in several hundred MHz of RF in real time; and simultaneously captures,
retrieves, and isolates VWB Digital Intermediate Frequency (DIF) data at full
ingest rate. Blade Server technology in conjunction with high performance 10
Gigabit Ethernet switch data distribution capabilities allow processing
capabilities to be extended and system footprint to be reduced.
Each Lighthouse stream is composed of four components: acquisition (ACQ), pulse
characterization (PDW), Pulse Doppler characterization (SDW), and DIF storage/retrieval.
The ACQ component performs digitization of analog input data, or reformatting
of digital input data.
The PDW component analyzes several hundred MHz of RF in real time, and produces
pulse descriptor words suitable for both automatic and manual follow-on
processing. The SDW component detects CW signals in the input signal and
produces stream descriptor words. Both provide multi-dimensional displays
that allow the user to visualize large volumes of data in real-time. Zooming in on
frequency or time is achieved by rubber-banding a region of interest.
Zooming out to the previous region (remembered on a LIFO queue) is a single
The DIF component captures, retrieves (full bandwidth or sub-band tuned),
and isolates VWB Digital Intermediate Frequency (DIF) data at full ingest
Lighthouse employs a Web user interface that provides "one stop shopping"
for all control functions and status visualization.
