Claim 0:
1. A method for monitoring a physiological parameter in a person using a radar system, the method comprising:
performing stepped frequency scanning below the skin surface of a person using at least one transmit antenna and a two-dimensional array of receive antennas, the stepped frequency scanning being performed across a frequency range using frequency steps of a step size;
coherently combining digital data generated from the two-dimensional array of receive antennas and across the range of stepped frequencies to produce a pulse wave signal of the person;
changing a parameter of the stepped frequency scanning in response to a slope of the pulse wave signal;
performing stepped frequency scanning below the skin surface of the person using the at least one transmit antenna and the two-dimensional array of receive antennas and using the changed parameter; and
coherently combining digital data generated from the two-dimensional array of receive antennas and across the range of stepped frequencies to produce the pulse wave signal of the person.
