Principal Accomplishments

  • Lincoln Laboratory conducted a large-scale surface surveillance experiment with multiple airborne sensors, including electro-optic imagers and moving target indication radars. The objectives were to assess the feasibility of detecting and tracking difficult targets moving between open rural areas and cluttered urban environments, and to develop the required processing techniques and multiple-sensor data-fusion and handover concepts.
  • The Laboratory has developed techniques for detecting dismounted personnel and is researching the feasibility of discriminating between personnel and other target types. A field exercise to collect dismount radar phenomenology was planned and conducted.
  • Lincoln Laboratory's active experimental campaigns included several collections performed to demonstrate architectural concepts using an active electronically scanned array together with a battle management, command-and-control suite. The experiments were undertaken to demonstrate the ability of commanders to respond to the agile behavior of enemy targets in an emulated global-war-on-terror scenario. These efforts led to the insertion of fusion and exploitation tools into an experimental suite of capabilities used by the National Geospatial-Intelligence Agency.
  • In the advancement of ISR net-centric architectures, Lincoln Laboratory is evaluating and demonstrating the ability to search and discover information across multiple ISR federated systems. In addition, for the Distributed Common Ground System–Navy, the Laboratory has completed an enterprise architecture assessment that will help in framing the architecture for the objective system.
  • Lincoln Laboratory has developed new passive sonar beamforming algorithms for submarine bow sphere arrays. New computationally efficient approaches for conventional beamforming were developed and shown to outperform legacy systems. This modernization has enabled the application of adaptive beamforming for additional benefit in dense contact environments. The new approaches have demonstrated significant benefits with recorded Fleet data, and the Laboratory is working closely with the Navy and industry on algorithm technology transition.
  • wideband nonlinear equalization chipThe wideband nonlinear equalization chip runs at 4000 megasamples per second and compensates for nonlinear distortion to improve system dynamic range.
    The Laboratory completed a prototype microprocessor chip showing the ability to cancel nonlinearities commonly found in complex receiver systems. This capability will permit lower-performing analog-to-digital converters to be used without sacrificing performance.
  • In support of transitioning technology, sharing results with the community, and reaching national consensus, Lincoln Laboratory hosts several annual workshops that have had significant impacts on their respective communities: High Performance Embedded Computing, Integrated Sensing and Decision Support, Adaptive Sensor Array Processing, and Surface Surveillance Technology.
