  • Hypervelocity impact and time of arrival detection method and system
    Patent number: 8316690
    Abstract: A method and system for detecting hypervelocity impacts on a detection surface utilizes multiple sensors that directly measure electrical pulse radio frequency (RF) emissions generated by hypervelocity impacts on a detection surface and time of arrival (TOA) position measurements for determining the precise impact location on the detection surface. The detection surface material is compressed differentially in such a way that the inherent equalization of the compressed electron density in one area of the impact is directed to the uncompressed area of the material causing an electrical current that flows until the redistribution of the electrical charge has been completed and the rapid redistribution of charge and inherent current that results emits the radio frequency pulse that is induced into the detection surface.
