Aircraft System Swarms
New weapons technology is needed to combat the proliferation of small unmanned aircraft systems (sUAS), miniaturization of sensor technology, and advancement of UAS swarm logic that will enable swarms of sUAS to threaten US airbases by the 2025 timeframe.
- WIAMan Technology Demonstrator Sensor Codes Conforming
to International Organization for Standardization/Technical
Standard (ISO/TS) 13499
The Warrior Injury Assessment Manikin (WIAMan) Project is in the process of developing anthropomorphic test devices specific to the underbody blast environment and requires ISO Channel Codes specific to this test dummy.
- Beam Propagation Model Selection for Millimeter-Wave
Directed Energy Weapons
Comparing the relatively simple Fraunhofer or "far field" (FF) approximation commonly used in radar and high-powered microwave systems with the more complex near field (NF) propagation model based on the field equivalence principle demonstrates which approach achieves reasonable modeling fidelity with minimal compute power.
- Experimental Design of a UCAV-Based High-Energy Laser
Until now, unmanned combat aerial vehicles (UCAV) have used only conventional missiles (i.e., Hellfire), but the rapid growth of laser weapon technology suggests that the day of the first deployable UCAV armed with a high-energy laser (HEL) weapon is not far away.
