Patent ID: 7568430

Claim:
A battle damage assessment (BDA) system comprising: a weapon including at least one fragment transmitter to radiate a pulse upon detonation of the weapon; the transmitter further comprising: two electrodes; a ferroelectric material disposed between the two electrodes; a spark gap formed in the ferroelectric material connected to each electrode by a wire; and a resonant dipole transmitter in conjunction with the ferroelectric material to transmit at least one pulse upon weapon detonation that compresses the ferroelectric material; an antenna platform to receive the radiated pulse as a received pulse; and a processor to provide BDA based on the received pulse, wherein compression of the ferroelectric material causes de-poling by phase transformation to produce temporal voltage oscillations V of V=V 0 e −αt cos ω t , such that ω 2 = 1 LC - R 2 4 ⁢ L 2 , and α = R 2 ⁢ L , where L is inductance of the two wires, C is capacitance of the two electrodes, and R is a sum of R radiation and R loss such that R radiation is effective radiation resistance of the two wires, and R loss , includes other resistances of the transmitter.
