The ability to create light or dense EW
situations with multiple emitters on
multiple platforms, all with controlled
motions, together with high fidelity
generation of all individual emitters,
combine to create a powerful capability for
SLQ-32 test, evaluation, and training.
The simulator produces PDWs for up to 1000
simultaneous emitters at total pulse
densities of up to 2 million pulses per
second (2 Mpps) and beyond. The
core VariGen technology provides an extensive
repertoire of complex signal types, modulations,
and scan patterns. (More on signal
modeling...)
In addition to its standalone capability,
VariGenTM
for SLQ-32 can be operated as a
subsystem within the Navy's Next Generation
Simulator (NGS) for combat systems. This
means increased realism for Combat System
testing over and above test procedures relying
on canned scripts to simulate EW system
responses.
The VariGenTM
is transportable, weighing under 30 lbs, and can
be easily set up and connected to any SLQ-32
presorter (1A4 or, for ESE, 1A5)
unit. It is 19" rack mountable and
also fits on a ship's EW equipment shelf.
MIL-type connectors for cabling to the presorter
unit are located on simulator's rear
panel.
The hardware Base Unit of a VariGenTM
simulator is controlled over Ethernet by WindowsTM hosted
software. Simulation scenarios and
libraries can be constructed and checked on any
Windows desktop or notebook PC without the need
for simulation hardware to be present.
VariGenTM
for SLQ-32 features an ability to multiplex
"live" pulse descriptors coming from the
SLQ-32's own receiver/encoder units into its
synthetic PDW output stream. Thus the
simulator can superimpose a "background" or
secondary pulse load while an external signal
generator, replica radar, or live exercise
provides direct RF stimulation.
