1. A radio-frequency (RF) sensor, comprising:
an RF antenna; and
a processor operatively coupled to memory and configured to:
receive RF radiation via the RF antenna;
input, to a trained model, data indicative of characteristics of an RF signal among the RF radiation; and
based on an output from the trained model, determine at least one of:
a frequency of the RF signal;
a modulation type of the RF signal;
a power level of the RF signal;
a time period of reception of the RF signal at the RF sensor;
a signal-to-noise ratio (SNR) of the RF sensor;
an RF signal type of the RF signal;
an association of the RF signal with a type of RF source;
a deviation of the RF signal over time;
a deviation in operating condition of an RF source of the RF signal; and/or
that the RF signal is a new RF signal that is not associated with an operating environment in which the RF sensor received the RF signal,
wherein the processor is configured to, based on the output of the trained model, determine the deviation of the RF signal over time, and the deviation is in power level and/or SNR.
