Classification: CPC H | IPC H

Claim 17:
18. A method for field detection, comprising:
wirelessly transmitting power from a set of one or more transmitters to a set of one or more receivers, comprising transmitting propagating radio frequency (RF) radiation;
while transmitting the propagating RF radiation, at a detector, receiving a first latent scattering signal at a first time;
based on the first latent scattering signal, continuing to transmit propagating RF radiation, comprising, at a first set of one or more processing elements, classifying the first latent scattering signal as nominal; and
while transmitting the propagating RF radiation, at the detector, receiving a second latent scattering signal at a second time after the first time;
at a second set of one or more processing elements, classifying the second latent scattering signal as anomalous, comprising:
determining a spectral density of the second latent scattering signal; and
analyzing the spectral density, comprising classifying the spectral density as anomalous using a statistical classifier, wherein the spectral density is indicative of the anomalous condition; and

in response to classifying the second latent scattering signal as anomalous, altering transmission of the propagating RF radiation.
