    Testing Air and Missile Defense Radar

    APL teamed with industry and the Above Water Sensors Directorate of Program Executive Office Integrated Warfare Systems on two successful tests of the AN/SPY-6(V), a wideband digital beam-forming sensor known as the Air and Missile Defense Radar.

    Test Target Prototyping

    A cross-APL team of engineers, working with the Missile Defense Agency’s (MDA) Target and Countermeasures Directorate and other government and industry partners, develops cost-effective solutions for MDA to support live-fire testing of interceptors, sensors, and fire control systems.

    Uncrewed Surface Vessel Perception

    International regulations for preventing collisions at sea require vessels to operate within certain distances based on the visual identification of other vessels.

    Optical Communications at Sea

    We successfully demonstrated a high-bandwidth free-space optical (FSO) communications system between two moving ships, proving operational utility of FSO technology in the maritime environment.

    Situational Awareness for First Responders

    Under the direction of the Department of Homeland Security Science and Technology Directorate, APL partnered with the New York City Police Department’s Emergency Service Unit in April 2017 to field-test and evaluate a commercial Mobile Ad-hoc Networking (MANET) system.

    Standard Missile-3: The Next Generation

    APL led key “end-to-end” system-level performance analysis in collaboration with the government–industry team for the SM-3 Block IIA missile, cooperatively developed by the United States and Japan.

    Revolutionizing Prosthetics

    Revolutionizing Prosthetics is an ambitious multiyear program—funded by the Defense Advanced Research Projects Agency (DARPA)—to create a neurally controlled artificial limb that will restore near-natural motor and sensory capability to upper-extremity amputee patients.
