Thesis (Ph.D.)--University of Florida, 2009.

This dissertation begins with the spectral analysis of the non-linear Doppler phase modulation mechanism on which the non-contact vital sign detection is based. The harmonic and intermodulation issues caused by the non-linear Doppler phase modulation will be discussed in detail. Analyses will illustrate the method for optimal design of radio frequency and radio architecture. The theory will be verified by both numerical simulations and experiments using a Ka-band bench top system.

520 $a This dissertation begins with the spectral analysis of the non-linear Doppler phase modulation mechanism on which the non-contact vital sign detection is based. The harmonic and intermodulation issues caused by the non-linear Doppler phase modulation will be discussed in detail. Analyses will illustrate the method for optimal design of radio frequency and radio architecture. The theory will be verified by both numerical simulations and experiments using a Ka-band bench top system.
520 $a Making use of the non-linear Doppler phase modulation, a new method and system for non-contact measurement of frequency and amplitude of mechanical vibration is invented in this chapter. With very simple radio architecture, this method does not need the calibration of signal amplitude and has the ability of self-verification.
520 $a The non-contact Doppler radar measurement system has been integrated in both printed circuit board and CMOS integrated chip levels. The design, implementation, and characterization of the integrated radar system will be introduced in the subsequent chapters.
520 $a As a main source of noise, the random body movement has been limiting the wide application of this technology. In Chapter 6, a random body movement cancellation technique will be introduced to cancel out the noise caused by random body movement. Both the complex signal demodulation and the arctangent demodulation will be studied for random body movement. Theoretical and experimental results will demonstrate the advantages of complex signal demodulation for random body movement cancellation.
520 $a As an advanced signal processing method for Doppler radar non-contact vital sign detection, the RELAX algorithm will be discussed and used in experiment. It will be shown that the RELAX algorithm in general succeeds in mitigating the effects of the smearing and leakage problems of the periodogram caused by limited data length.
520 $a Finally, an application case study of infant vital sign monitor will be presented. (Full text of this dissertation may be available via the University of Florida Libraries web site. Please check http://www.uflib.ufl.edu/etd.html)
