ISA has been developing and deploying high performance, missions
critical processing systems for the US Government since 1997. The
systems built by ISA constitute the "heavy lifting" portions of our
customer's processing chain in terms of data rates and compute
intensity. The company's expertise includes:
ISA has deployed dozens of real-time processing systems designed to
detect and characterize unknown pulse and continuous-wave (CW)
waveforms in time series data at rates ranging from 25 million samples
per second (MS/s) all the way up to 1200 MS/s. Example DSP systems are
Floodlight (very wideband parameterizer), Spotlight (wideband
parameterizer), and BeachComber (CW processor). For each DSP system,
the company uses a combination of general purpose computers, FPGA-based
processors, and advanced software architectures.
ISA has extensive experience in automatic parameter estimation and
feature extraction for real-time systems. ISA's pulse and CW waveform
detection and characterization algorithms have been developed to
provide high sensitivity detection, high accuracy parameter estimation,
and low false report rates in a purely automatic mode. These algorithms
have been optimized using both simulated and real data and are capable
of dealing with many difficult real-world conditions such as
interfering signals and non-stationary effects. Below are intermediate
time and frequency data processing products from the automated
algorithms that are used for estimating signal parameters.

ISA utilizes OSP when a DSP solution is either not available or is cost
prohibitive. The Optical Energy Detector (OED) was the company's first
OSP application. The OED used an acousto-optic modulator and the
Fourier transform property of a lens to generate the Power Spectrum
(PS), and employed a high-speed camera and framegrabber to digitize the
PS. ISA also developed an Optical Correlator for performing a
million-point correlation on wideband signals in real time. The OC
module is rack-mountable and has a throughput of 0.6 TFLOPS.
ISA implements decoupled architectures through extensive use of: the
messaging paradigm, the publish-subscribe model, the service
configurator pattern, shared object libraries, and pipelining. High
performance computing is achieved by parallelizing the problem, mapping
work to thread pools, and running on multi-core blade servers.
ISA's product line of graphical user interface displays provide
creative visualization of real-time, high bandwidth data streams.
ISA is developing two systems that can provide significant intelligence
products to the defense, intelligence, and homeland security
communities. The first is a Tactical SIGINT System (TSS) designed to
provide Force Protection / Force Multiplication for the War-fighter in
theater. The second system is the Wide Area Video Camera (WAVcam) that
has application in Border Security as well as a military Force
Protection role. The WAVcam also has civil security applications for
large areas such as airports, industrial facilities, or public events.
