Proliferation of low cost enemy drones are driving the need for new and innovative sensors and systems to sense and neutralize enemy drones threats at greater ranges, while reducing costs. The United States Army (USA) and other DoD agencies would benefit from a network of low-cost sensors used to form a C-UAS perimeter in order to prevent swarming enemy UAS platforms from penetrating and operating in the protected airspace. TSC is proposing to build on positive Phase I results of the Distributed UAS Neutralization and Exclusion System (DUNES) study using existing ground and airborne sensor designs. We propose to perform two low-risk prototype demonstrations of the DUNES capabilities. The first demonstration will validate sensor performance when integrated as a system and ensure the track quality is sufficient to enable the DUNES performance. Figure 2.1-1 depicts the C-UAS Sensor Demonstration configuration. For the second demonstration, TSC has partnered with Lockheed Martin Missiles and Fire Control (LM-MFC) to provide the Altius airframe integrated with an Aquila sensor as well as the FAAD C2 with RESI. Figure 1.2-2 depicts the C-UAS DUNES Demonstration configuration.
