Raytheon is a significant player in the US defense industry.
LispWorks is used at Raytheon in work that implements a signal processing analysis pipeline, complete with live graphical displays, high performance FFTs, and signal processing blocks that can be strung together for the development of algorithms.
SigLab simulates an incoming warhead intercepted by the Exo-atmospheric Kill Vehicle
David McClain of Raytheon says 'The screenshot shows our SigLab system running a simulation of an incoming nuclear warhead (all exo-atmospheric), and at 40 seconds into the run you see in the middle left 2-D Sonogram display the effects of a nearby warhead exploding and heating up the target being tracked. This analysis was used at Raytheon to develop advanced rapid detection and discrimination systems for targeting incoming nuclear warheads on our EKV project (Exoatmospheric Kill Vehicle).'
David adds 'Using LispWorks made it easy to analyse the resulting graphs. The system is capable of solving any computable system of difference equations. The result is an astonishing simplification for the user in two dimensions of program complexity. LispWorks, with its powerful FLI and very high performance math, makes the system quite responsive. This is a truly elegant and incredibly useful system. It is in current use at Raytheon and about to get even bigger. It is capable of solving not only difference equations but also production flow and even management report flow.'
