Abstract:
1. A system for determining impact point and damage propagation faults in a detection surface utilizing frequency domain reflectometry (FDR), comprising: a detection surface having a conductive layer capable of propagating radio frequency (RF) signals; at least one signal transmit/receive port on said detection surface for injecting a radio frequency (RF) interrogation signal into said detection surface and at least two signal receive-only ports on said detection surface spaced a distance apart from each other and from said signal transmit/receive port for receiving reflected radio frequency (RF) signals of said injected interrogation signal; and frequency domain reflectometry measurement means coupled with said transmit/receive port and said at least two signal receive-only ports operational to measure frequency responses of said ports compared to predetermined baseline measurements and determine a precise location of an impact point and damage propagation fault in said detection surface by triangulation.
