Problem:

A manufacturer of SIGINT systems needed to develop a network of signal processing, analysis and graphics subsystems for a large 400+ processor communications and surveillance system. The critical nature of the application demanded numerous requirements that had to be met in the areas of user interface design, signal processing, subsystem communication, global networking, and highly distributed processing architectures.

Pictured is the control room for a large SIGINT system.

Twelve channel Digitizer unit employing a Sun Sparc processor and several Digital Signal Processors.

One of six, dual channel A/D cards with an embedded 56000 DSP time-base error corrector processor.

240 MFlop FFT windowing processor.

Multi-channel Spectrogram graphics card for a Sun analysis workstation. One of the many signal processing, analysis and graphics subsystems we developed as an integral part of our solution.

One of 120, 16GB Transputer-based Memory Control Processors.

Solution:

The final design incorporated GUI, DSP, and control software for the Windows and Unix-based workstations and embedded processors that made up this immense network. In addition, we created a real-time operating system and application code for the network of over 400 transputers that would comprise part of the system. We also developed numerous Windows and transputer network applications for a several-hundred-GByte memory system, a custom Spectrogram Graphics Card for the workstations, as well as an embedded 56000 DSP time-base error corrector.
