Advanced Signal and Embedded Processing

New concepts in modeling and simulation, speech processing, and radio frequency and acoustic processing revolutionize the military technology by allowing for higher fidelity testing of hardware and software, reduced workload for human operators, and easier detection of enemy targets.

Objectives

We develop advanced signal-processing concepts that can impact Lockheed Martin sensors, mainly radio frequency and acoustic, by an order of magnitude. Also important are processing implementations. Customers include the Defense Advanced Research Projects Agency (DARPA), Air Force Rome Laboratory, (AFRL), Office of Naval Research, and Naval Research Laboratory.

Key Technologies

• Modeling and simulation (M&S): In the 1990s, we were the prime contractor for DARPA's Rapid Prototyping of Application-Specific Signal Processors (RASSP)—a $60-million effort to improve the process of developing electronic systems, of which a key element was M&S capability. Based on earlier work, RASSP program, and recent investments, we have a very powerful M&S tool called CSIM that can be used effectively on embedded processing the network systems.
• Speech processing: We have a rich legacy of developing speech-processing algorithms for a variety of uses. Our capability is speaker-dependent, spoken-word command recognition. We also develop signal-intelligence and speaker-recognition algorithms.
• Radio frequency and acoustic processing: Our signal-processing technology is pushing the state-of-the-art in new covert waveforms for communication, techniques for virtual Doppler shift, and space-time coding of radar and communication waveforms and acoustic processing for underwater communication.

Applications and Transition Opportunities

• Speech Processing: We are taking AFRL's speaker-recognition algorithms, porting them to GEDAE™, and making enhancements.
• Speech Processing: For Lockheed Martin Aeronautics, we are developing a speaker-dependent, command-word recognizer that will significantly reduces pilot workload and allow them to pay closer attention to the combat environment.
• F-35 Joint Strike Fighter Integrated Core Processor (ICP) M&S: Using our CSIM to model the ICP allows Lockheed Martin Maritime Systems and Sensors-Eagan to verify their processing architecture by mapping software onto a virtual architecture and simulating execution.
• Performance Modeling: We are supporting Lockheed Martin Aeronautics in evaluating their system-integration laboratory architecture for the F-35 avionics integration and testing effort.
• Modeling and Simulation: Our available CSIM product models and simulates a wide range of highly complex software programs, from avionics integration to mobile communications networks.
• Speech Recognition: Collaborating with departments within ATL, we are rapidly expanding and integrating speech processing; speech recognition; and natural, intuitive, verbal interaction with intelligent systems.
