Claim 30:
31. A system for monitoring a physiological parameter in a person, the system comprising:
a radio frequency (RF) front-end including at least one transmit antenna and a two-dimensional array of receive antennas, the RF front-end configured to perform stepped frequency scanning across a frequency range using frequency steps of a step size, the stepped frequency scanning performed using the at least one transmit antenna and the two-dimensional array of receive antennas; and
processing circuits configured to generate data that includes amplitude and phase data in response to radio waves received by the RF front-end and to coherently combine the generated data across the two-dimensional array of receive antennas and across the range of stepped 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 stepped frequencies includes comparing the pulse wave signal to a periodic signal model.
