Novel Methods to Measure Penetrator Dynamics in Multi-Layer Geometries

This proposal describes an approach to meeting DTRA’s goals of improving sensor technology for penetrating weapons. Weidlinger Associates Inc. (WAI) has significant experience in the design and use of ultrasound technologies for a broad range of end-use applications. WAI is also familiar with the terradynamic issues related to penetrators and the targeting aspects through its work in Hard Target Defeat projects over the last ten years. WAI proposes to combine its expertise in impact and penetration dynamics and in ultrasonic/acoustic sensors design to develop an effective acoustic sensor design for penetrating weapons during this Phase I effort. The sensor will provide measurement data that will contribute to (a) distinquishing the acoustic signature of different materials during penetration, (b) quantifying the operating environment (frequencies, noise levels, etc.) of sensors onboard a penetrator and (c) guide improvements in the acoustic sensor's design in later development phases.
