  • Multi-grid Analysis of the Three-Dimensional Doppler Radar Radial Velocity: Idealized Cases Study

    Through idealized experiments, this study is to test the performance of multi- grid three-dimensional variantional (3D-Var) on three-dimensional (3D) Doppler radar radial velocity data assimilation, and to what degree the 3D Doppler radar radial velocity can improve the conventional (in situ) wind observation analysis. A two-scale idealized wind field is constructed, and then random- distributed conventional wind data and 3D Doppler radar radial velocity data are generated based on this idealized wind field. By assimilating these data and comparing the analyses with the true idealized circulation field, the multi-grid 3D-Var performance in 3D Doppler radar radial velocity analysis is evaluated. The effects of weak constraint and strong constraint on the multi- grid 3D-Var analyses are also presented. Results show that the 3D Doppler radar radial velocity data do provide additional useful information especially in the sparse distributed conventional observation situation, and the multi- grid 3D-Var with strong constraint can make better analyses on not only horizontal but also vertical velocity.

  • A novel interferometric millimeter wave Doppler radar architecture

    A universal, mixerless millimeter wave (mmW) Doppler radar architecture consisting of simply a Continuous Wave (CW) source and an intensity detector based on optical interferometry technique has been assembled. The phase information is obtained by using an oscillating mirror in the reference arm, similar to that used by the FTIR (Fourier Transform Infrared spectroscopy) technique. The reference mirror oscillates at a frequency that is higher than twice the Doppler frequency of the object. Rigorous mathematical formulas have been derived to solve for both the amplitude and the phase of the Doppler signal, by using the Low-Frequency-Band (LFB) and High-Frequency-Band (HFB) signals. The Doppler frequency signature of a moving object can be obtained from the Fourier transform of the phase. A prototype at 94 GHz was built and tested using a ball pendulum target moving over a full-swing distance much smaller than a wavelength. Both the measured amplitude and phase have been shown to agree well with the experimental parameters. The interferometric Doppler radar architecture is universal and can be extended to THz without significant change of components.

  • Vital signs modeling for Doppler radar cardiorespiratory monitoring

    Microwave Doppler radar system is utilized to sense breathing and heartbeat of human beings to monitor their vital conditions. The Doppler radar not only receives vital sign signals but also acquires different additive and unwanted waves such as the signal of the extra motion of the body, clutter and electromagnetic noise. Making a mathematical model of received signal by a Doppler radar will be helpful to analyze vital conditions. In this paper we simulated the signal received by a Doppler radar system, and the results were compared with the vital signals obtained from a human by both a custom designed 24 GHz radar and a commercial respiratory transducer attached around the chest; in both time and frequency domains.

  • Noncontact Doppler radar unique identification system using neural network classifier on life signs

Our work shows the possibility of non-contact unique identification where camera based system is not preferred. It is demonstrated that the system is capable of identifying individuals with more than 90% accuracy. This study also has impact on radar- based breathing pattern classification for health diagnostics.

  • Detection of Moving Target and Localization of Clutter Using Doppler Radar on Mobile Platform

    This letter explores the possibilities of detecting a moving target and localizing clutter using nonstationary Doppler radar. The detection of a moving target, particularly a human, has many potential applications in the fields of surveillance and rescue. In dangerous environments, Doppler radar can be used to effectively collect information about the surroundings, even through walls. However, a moving platform makes the detection of a moving target complicated due to Doppler shift caused by the clutter. We analyze the pattern of the Doppler shift due to clutter over time and develop a linear regression model that describes this pattern. The location of clutter can be estimated by the model with the time history of the measured Doppler shifts. Although the pattern from clutter follows the mathematical model, the pattern from a moving target does not, resulting in a high-percentage root-mean-square (RMS) fitting error. On the basis of the percentage RMS fitting error, a moving target is differentiated from clutter.

  • Sub-μW signal power doppler radar heart rate detection

    Periodic motion, such as that resulting from cardiopulmonary activity, can be measured by direct-conversion microwave Doppler radar. In such systems, motion is measured as phase modulation and measurement sensitivity is significantly affected by phase noise and amplitude modulation sidebands in the local oscillator. Presented here are experimental results of heart rate measurements under various signal output power conditions, with consideration for the impact of respiration. Measurements were made using a custom compact quadrature direct conversion Doppler radar circuit, and results indicate that heart rate can be accurately assessed with transmit power for levels as low as 20nW for a subject distance of one meter. This is the lowest power ever reported for ISM band CW doppler radar heart beat detection.

  • A 60-GHz CMOS direct-conversion Doppler radar RF sensor with clutter canceller for single-antenna noncontact human vital-signs detection

    This paper presents a 60-GHz CMOS direct-conversion Doppler radar RF sensor with a quasi-circulator (QC) and a clutter canceller circuit for single- antenna noncontact human vital-signs detection. A high isolation QC is designed to provide better detection sensitivity for the tiny vital-signs detection for the single-antenna Doppler radar architecture. The clutter canceller performs cancellation for the transmitting leakage power from the circulator and the background reflection clutter to enhance the detection sensitivity of weak vital signals. The measurement shows that the total transmitting power is 3 dBm while the conversion gain of the sub-harmonic receiver is 10.5 dB. In the human vital-signs detection measurement, at a distance of 75 cm, the detected heartbeat (1-1.3 Hz) and respiratory (0.35-0.45 Hz) signals can be clearly observed. The RF sensor is fabricated in 90-nm technology with a chip size of 2 mm × 2 mm and a consuming power of 217 mW. The presented CMOS vital-signs Doppler radar RF sensor will be very useful for the wireless remote physiological monitoring healthcare system and the tiny vibrations detection applications.

  • AC/DC coupling effects on CW and pulse transmission modes in Doppler radar physiological monitoring system

    Direct-conversion CW microwave Doppler radar can be used to wirelessly detect cardiopulmonary activity. One of the limitations of homodyne CW Doppler radar systems for physiological monitoring is large DC offset in baseband outputs. The common method to avoid the DC offset is AC coupling. While AC coupling removes the DC offset efficiently, it introduces large settling time and signal distortion in baseband. In this paper we explore the use of direction conversion pulsed Doppler radar to overcome this issue. Performance of CWand pulse radar is compared using mechanical target movement which simulates respiratory motion. The results demonstrate while AC coupling distorts CW radar output, it has a negligible effect on pulse radar output.

  • Amplitude modulation issues in Doppler radar heart signal extraction

    Medical Doppler radar research has largely been limited to obtaining respiratory and heart rates. While this information is vital for many applications, medical Doppler radar signatures carry significant other information that could lead to cardiopulmonary volume assessments, including cardiac stroke volume (SV), and cardiac output (CO). Accurate recovery of heart signal amplitude is required for these assessments. This paper presents the first analysis of amplitude modulation artifacts on heart signal recovery in Doppler radar systems. The sources of amplitude modulation artifacts are identified, including limitations of linear demodulation, and inherent affects of respiratory signal harmonics on heart signals. Experimental and simulation results demonstrate the validity of this analysis, and outline the path towards successful heart signal amplitude recovery.

  • A Demonstrator for the Doppler Radar Cloud Profiler (DRCP)

    Millimetre wave radar, preferrably with Doppler capability, is applied in atmospheric remote sensing since decades. The first systems were based on vacuum tube technology and used the pulsed Doppler operation mode. Due to the high manufacturing and operation costs, there was no reasonable path foreseen to routine operational application, e.g. in networks of national weather services, to date. In the mid-1990s the first millimetre-wave radar profilers for atmospheric research based on solid-state devices were developed. They used the FMCW Doppler operation mode. Due to their complex RF design these systems were not suitable for operational operation, either. Recent progress in the performance and availability of Ka-band solid state components encouraged S&AO Ltd to develop an RF design for a Ka-band FMCW Doppler Radar Cloud Profiler (DRCP) for future operational application. This RF design is presented here. A demonstrator for the DRCP has been realised during a Proof of Concept project. The DRCP demonstrator performance was assessed by inter- comparison with an established cloud radar. The result of this performance assessment is described, and eventually conclusions are presented.
