Claim Text:
1. A method for remotely sensing cardiac-related data of an animal subject, the method comprising: transmitting a radio frequency signal to impinge on tissue of the subject; receiving a reflected radio frequency signal, the reflected radio frequency signal comprising a reflection of the radio frequency signal impinged on the tissue of the subject; generating baseband data utilizing the reflected radio frequency signal; filtering multiple parallel streams of data embodying or derived from the baseband data to yield initially filtered data including a plurality of initially filtered data sets, wherein each initially filtered data set is obtained by filtering a stream of data of the multiple parallel streams of data with a different filtering scheme, and each filtering scheme includes high-pass filtering with a cutoff frequency of 10 Hz or greater; performing waveform phase position determination on data embodying or derived from the initially filtered data to yield waveform phase position determined data; performing at least one auto-correlation of the waveform phase position determined data to yield auto-correlated data; determining periodicity of data embodying or derived from the auto-correlated data, wherein said determining of periodicity comprises determining a plurality of periodicity values; and computing heart rate including selecting a majority or median of the plurality of periodicity values.
