ABSTRACT:
Apparatus and method for remotely detecting super-low frequency (SLF) and extremely-low frequency (ELF) signals eminating from human subjects. The SLF/ELF signals are composed of various wavelengths and amplitudes which correspond to the subjects internal physiological processes. The apparatus includes: a supercooled multi-plate arrayed antenna for detecting the SLF/ELF signals; an analog signal conditioner unit adapted to filter out signals having a frequency of greater than 40 Hertz; and a digital signal processor unit adapted to perform Fast Fourier Transform and autocorrelation signal analyses for separating signal wavelengths and amplitudes which correspond to the internal physiological processes and represent EKG, EEG, EMG, EOG and respiration measurements.
