  • Doppler Radar Physiological Assessments

    The Doppler radar detects all motion in the radar field of view, through detection of phase variations in the received signal. The challenge in physiological monitoring via Doppler radar is to effectively isolate the subject's random fidgeting physiological motion. The percentage of measurement interval containing significant motion may be used as a measure of subject rest/activity cycle, determining the degree of restlessness, for example, actigraphy. Phase demodulation provides the output proportional to chest displacement, and this information can be further analyzed to extract respiratory and heart rates, analyze the shape of respiratory signals, assess heart rate variability (HRV) parameters, and estimate displacement amplitude and related respiratory volume. The magnitude of received RF power can be analyzed to determine cardiopulmonary radar cross section (RCS) and further determine subject orientation. The variation of RCS with size and curvature of the target surface is the basis for detecting orientation of a human subject.

  • Physiological Doppler Radar Overview

    This chapter introduces system¿¿¿level analysis of the Doppler radar system for physiological sensing. The design considerations and performance trade¿¿¿offs were discussed for radio frequency (RF) front¿¿¿end, baseband, and signal¿¿¿processing modules of the system. The chapter explains the need for quadrature receiver in the context of physiological monitoring, as well as associated trade¿¿¿offs including channel imbalance, DC offset, baseband coupling, phase demodulation, and noise issues. It presents graphical representation of quadrature outputs to explain trade¿¿¿off of frequency operation, effects of channel imbalance and AC coupling, and demodulations methods. The operation frequency and power requirements were analyzed in terms of component availability, safety, and penetration into human tissue. The chapter introduces signal¿¿¿processing methods commonly used for rate extraction, including peak detection, fast Fourier transform (FFT), and autocorrelation. Finally, it discusses noise sources that cause signal¿¿¿to¿¿¿noise ratio (SNR).

  • Physiological Motion and Measurement

    Respiratory, heart, and circulatory movements that can be detected without contact by Doppler radar are concentrated not only in the thorax, where the lungs and heart lie, but they also occur in the abdomen, which moves during respiration, and at other points on the body where superficial pulses are present. This chapter first describes the motion associated with breathing and how this motion affects the skin surface motion. It then discusses the location and anatomy of the heart, the electrical and mechanical events that cause contraction, the motion of the heart during contraction, and how that motion affects chest wall motion. The chapter also describes the location and structure of the arteries and veins, how they distend as the blood pressure varies during the cardiac cycle, and how this distension affects the skin surface motion. Doppler radar measurement of heart and respiration is a measurement of surface motion.

  • Advanced Performance Architectures

    This chapter discusses advance performance architectures that overcome issues of DC offset, spectrum folding, motion interference, and range detection. It describes three different approaches to overcome DC offset and spectrum folding include single¿¿¿channel homodyne system with phase tuning, heterodyne system with frequency tuning and low¿¿¿intermediate frequency (IF) architecture. Due to extremely small physical motions of human chest during respiration, the Doppler radar system for physiological monitoring has to be very sensitive to phase changes, which are caused by path length variations. A fundamental limitation of continuous¿¿¿wave (CW) radar is the inability to discriminate range to target. Either frequency¿¿¿modulated continuous¿¿¿wave (FMCW) or ultra¿¿¿wideband (UWB) radar can be used to detect both range to target, and target micro¿¿¿Doppler behavior. The chapter also describes a UWB impulse radar that can provide high¿¿¿resolution range profiles, as well as micro¿¿¿Doppler detection capability.

  • Introduction

    The development of Doppler radar for remote sensing of vital signs, with proof of concept demonstrated for various applications, could offer a platform for unobtrusive, noncontact, yet continuous physiological monitoring systems. Early identification of patient deterioration is important, as it can prevent subsequent cardiopulmonary arrest and reduce mortality. Assessment of cardiopulmonary functions is most often performed with contact sensors when direct access to the subject is available. Monitoring the cardiac state of burn victims can be challenging because it is sometimes difficult to find enough skin on which to apply an electrocardiogram (ECG) electrode. Cardiopulmonary activity is the main parameter used in the study of sleep disorders. Widespread use of microwave technology and digital processors in common household communications devices has driven down costs, making it possible to develop practical radar monitors that cost significantly less than conventional cardiopulmonary assessment instruments.

  • CW Homodyne Transceiver Challenges

    Continuous¿¿¿wave (CW) homodyne radar has been the most commonly used architecture for physiological monitoring, due to its ease of implementation. This chapter shows the simplified block diagram of a physiological radar, indicating radio frequency (RF) front¿¿¿end, baseband, and signal processing modules. It examines specific challenges related to each of those modules. The chapter describes the single¿¿¿channel system limitations. Since a quadrature receiver system and the two orthonormal output signals enable to measure the relative phase information accurately, it is used in various applications, including digital communications and Doppler radar. The chapter also describes arctangent demodulation with DC offset compensation to combine quadrature outputs. It presents relevant quadrature receiver theory and arctangent demodulation with center tracking DC compensation method. Experimental results demonstrating that center tracking is suitable for demodulation of small and large displacement are presented.

  • Radar Principles

    Advances in radar system hardware and software have enabled radar systems to detect, differentiate, classify, image, and track the range, altitude, direction, or velocity of multiple moving or fixed targets simultaneously. A radar system has a receiver intended to detect the reflected electromagnetic waves, indicating an object with a different dielectric constant in the propagation direction. Doppler radar is typically used to detect moving targets, and estimate their velocity. Security systems motion detectors and door openers are common uses of Doppler radar¿¿¿based motion detectors. There are two basic radar configurations based on the spatial relationship between the transmitting and receiving antennas: monostatic and bistatic. The major areas of radar application are briefly described, including military defense and weapons systems, remote monitoring of the Earth's surface, the ocean, and other planets, reconnaissance imaging, ground¿¿¿penetrating radar for archeological expeditions, weather surveillance, air traffic control, and others.

  • Sources of Noise and Signal¿¿¿to¿¿¿Noise Ratio

    This chapter derives signal¿¿¿to¿¿¿noise ratio (SNR) of the continuous¿¿¿wave (CW) Doppler radar system for physiological monitoring. This derivation assesses the theoretical limits of the radar system and determines the factors that affect the limits so that design decisions can be made appropriately. The radar equation is used to estimate the received power, taking into account the range to the target, the transmitted power, the radar cross section (RCS), the antenna gain, the wavelength, and the range. Noise sources include radio frequency (RF) phase noise from the oscillator, environmental thermal noise, and baseband 1/f noise of the mixer and of the baseband signal¿¿¿conditioning circuits. The SNR depends on the amount of noise at the mixer output from each of these sources. The chapter analyzes the variation of SNR with range, RCS, and the amount of physiological motion. It describes the effects of near¿¿¿field operation on the antenna gain.

  • Applications and Future Research

    Radar technology for sensing of physiological motion has reached the point of adoption for basic commercial applications in medicine and security. This chapter gives a brief review on some existing US Food and Drug Administration (FDA)¿¿¿approved and other commercial devices followed by ongoing research efforts. Ongoing research in the field is directed toward broader, more robust applications of remote sensing of physiological motion. Remote sensing of heart rate, respiratory rate, and gross bodily motion has been demonstrated using radar technology in monitoring systems, which makes no contact with the patient. Doppler radar can be used to detect motion ranging from arbitrary limb movement to periodic chest displacement associated with cardiopulmonary activity. Technology that can capture minute changes in physiological parameters has proven highly effective at assessment of sleep in elaborate and expensive sleep laboratory studies.
