Claim 0:
1. 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 Doppler information based on the second latent scattering signal and analyzing the Doppler information, wherein:
the Doppler information is indicative of a Doppler shift exceeding a threshold amplitude and exceeding a threshold frequency shift magnitude; and
the second latent scattering signal is classified as anomalous based on the Doppler shift exceeding the threshold amplitude and exceeding the threshold frequency shift magnitude; and

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