1. A system for monitoring a physiological parameter in a person, the system comprising:
a frequency synthesizer configured to generate radio waves across a range of radio frequencies;
at least one transmit antenna configured to transmit the radio waves below the skin surface of a person;
a two-dimensional array of receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves; and
processing circuits configured to generate data in response to the received radio waves and to coherently combine the generated data across the two-dimensional array of receive antennas and across the range of radio frequencies to produce a pulse wave signal of the person;
wherein coherently combining the generated data across the two-dimensional array of receive antennas and across the range of radio frequencies includes comparing the pulse wave signal to a periodic signal model.
