16. A method for non-invasive monitoring of a subject's heart, the method comprising:
transmitting at least one transmitted RF signal toward a subject by an RF transmitting antenna, wherein the at least one transmitted RF signal comprises:
a first RF chirp within a range of frequencies extending from a first RF chirp frequency to a second RF chirp frequency, wherein the second RF chirp frequency is greater than the first RF chirp frequency, and
a second RF chirp within a range of frequencies extending from a third RF chirp frequency to a fourth RF chirp frequency, wherein the fourth RF chirp frequency is greater than the second RF chirp frequency;
receiving, by an RF receiving antenna, at least one received RF signal transmitted by the RF transmitting antenna and modified by the subject, wherein the RF transmitting antenna and the RF receiving antenna are located on opposing sides of a planar projection of the subject's heart;
controlling the transmitting of the at least one transmitted RF signal and receiving of the at least one received RF signal by a processing circuit; and
determining, based on the at least one received RF signal, at least one physiological parameter of the subject.
