  • Battle damage assessment system
    Patent number: 7568430
    Abstract: A shock-triggered warhead fragment transmitter is described. The transmitter is designed to radiate a pulse upon either detonation of the warhead or impact of the fragment with the target. The pulse energy is obtained by shock de-poling of a ferroelectric material and is radiated using a dipole antenna. Detection of the radiated pulses may be used to confirm detonation of the warhead and determine the time and location of the detonation and facilitate battle damage assessment.
    Type: Grant
    Filed: October 1, 2008
    Date of Patent: August 4, 2009
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Kenneth A. Conley, Raymond M. Gamache, Jason T. Drotar
