    abstract = {Sounds caused by the action of the heart reflect both its health as well as deficiencies and are examined by physicians since antiquity. Pathologies of the valves, e.g. insufficiencies and stenosis, cardiac effusion, arrhythmia, inflammation of the surrounding tissue and other diagnosis can be reached by experienced physicians. However, practice is needed to assess the findings correctly. Furthermore, stethoscopes do not allow for long-term monitoring of a patient. Recently, radar technology has shown the ability to perform continuous touchless and thereby burden-free heart sound measurements. In order to perform automated classification of the signals, the first and most important step is to segment the heart sounds into their physiological phases. This paper examines the use of different Long Short-Term Memory (LSTM) architectures for this purpose based on a large dataset of radar-recorded heart sounds gathered from 30 different test persons in a clinical study. The best-performing network, a bidirectional LSTM, achieves a sample-wise accuracy of 93.4% and a F1 score for the first heart sound of 95.8%.

    abstract = {Objective: Radar technology promises to be a
    touchless and thereby burden-free method for continuous
    heart sound monitoring which can be used to detect cardiovascular
    diseases. However, the first and most crucial step
    is to differentiate between high- and low-quality segments
    in a recording to assess their suitability for a subsequent
    automated analysis. This paper gives a comprehensive
    study on this task and firstly addresses the specific characteristics
    of radar-recorded heart sound signals. Methods:
    To gather heart sound signals recorded from radar, a
    bistatic radar system was built and installed at the university
    hospital. Under medical supervision, heart sound data
    were recorded from 30 healthy test subjects. The signals
    were segmented and labeled as high- or low-quality by a medical expert. Different state-of-the-art pattern classification
    algorithms were evaluated for the task of automated
    signal quality determination and the most promising one
    was optimized and evaluated using leave-one-subject-out cross-validation. Results: The proposed classifier is able to
    achieve an accuracy of up to 96.36% and demonstrates a
    superior classification performance compared to the stateof-
    the-art classifier with a maximum accuracy of 76.00 %.
    Conclusion: This paper introduces an ensemble classifier
    that is able to perform automated signal quality determination
    of radar-recorded heart sound signals with a
    high accuracy. Significance: Besides achieving a higher
    performance compared to state-of-the-art classifiers, the
    presented study is the first one to deal with the quality
    determination of heart sounds that are recorded by radar
    systems. The proposed method enables contactless and
    continuous heart sound monitoring for the detection of
    cardiovascular diseases.

    abstract = {Accurate and precise knowledge of the relative permittivity of printed circuit board (PCB) materials is essential for the reliable design of high-frequency circuits. For simplicity reasons, planar, resonant permittivity sensors, which are directly integrated on the unknown PCB material, are widely used. However, the sensors are affected by the nonidealities of the copper-clad laminate and PCB manufacturing process, e.g., the difference in roughness between the top and bottom sides of each metal layer. This paper analyzes the influence of these nonidealities on the extracted relative permittivity values of different sensor geometries in microstrip and substrate integrated waveguide (SIW) technology up to 100 GHz. Microstrip resonators are very sensitive against the investigated nonidealities. Additional roughness measurements and more detailed simulation models cannot noticeably reduce the uncertainties. SIW cavity sensors are more robust, and simple modeling approaches lead to low uncertainties smaller than 0.05 for the whole frequency range from 10 to 100 GHz.},

    Vital parameters are key indicators for the assessment of health. Conventional methods rely on direct contact with the patients’ skin and can hence cause discomfort and reduce autonomy. This article presents a bistatic 24 GHz radar system based on an interferometric six-port architecture and features a precision of 1 µm in distance measurements. Placed at a distance of 40 cm in front of the human chest, it detects vibrations containing respiratory movements, pulse waves and heart sounds. For the extraction of the respiration rate, time-domain approaches like autocorrelation, peaksearch and zero crossing rate are compared to the Fourier transform, while template matching and a hidden semi-Markov model are utilized for the detection of the heart rate from sphygmograms and heart sounds. A medical study with 30 healthy volunteers was conducted to collect 5.5 h of data, where impedance cardiogram and electrocardiogram were used as gold standard for synchronously recording respiration and heart rate, respectively. A low root mean square error for the breathing rate (0.828 BrPM) and a high overall F1 score for heartbeat detection (93.14%) could be achieved using the proposed radar system and signal processing.

The transition comprises two sub-transitions: one from the MSL to a substrate integrated waveguide (SIW) and the second from the SIW to the RWG. Both are on the same substrate and can be manufactured with a standard printed circuit board process. This leads to a very cost-effective solution compared with other approaches. A WR-42 waveguide can easily be surface mounted to the transitions using a standard flange. The transitions have been fabricated, and their measured performance shows good agreement with the simulations. The MSL-SIW transition has a broadband behavior and the SIW-RWG transition still reaches a relative bandwidth of 10%.},

The results indicate in which way antenna arrangements and beam alignments affect the signal quality and what MCS fulfills the train environment requirements best. Finally, the identified setup is selected and a recommendation for further research activities and tests on a rail vehicle in operation is made.

Measurements of all individual components and the final array antenna were taken to confirm the simulations and to prove the concept.

This can be achieved by monitoring the carotid artery or rather the carotid pulse signal. Commonly, ultrasound devices are used for that purpose. However, these devices are costly, mostly stationary and their usage requires training and experience. This paper investigates the possible usage of radar systems as a contactless and low-cost alternative for carotid pulse measurements. Theoretical investigations reveal a linear relationship between the measurands of both devices and synchronous recordings from three test persons further confirm the feasibility of using radar systems as a potential device for monitoring cardiovascular diseases.},

    abstract = {This paper introduces heart sound detection by radar systems, which enables touch-free and continuous monitoring of heart sounds. The proposed measurement principle entails two enhancements in modern vital sign monitoring. First, common touch-based auscultation with a phonocardiograph can be simplified by using biomedical radar systems. Second, detecting heart sounds offers a further feasibility in radar-based heartbeat monitoring. To analyse the performance of the proposed measurement principle, 9930 seconds of eleven persons-under-tests' vital signs were acquired and stored in a database using multiple, synchronised sensors: a continuous wave radar system, a phonocardiograph (PCG), an electrocardiograph (ECG), and a temperature-based respiration sensor. A hidden semi-Markov model is utilised to detect the heart sounds in the phonocardiograph and radar data and additionally, an advanced template matching (ATM) algorithm is used for state-of-the-art radar-based heartbeat detection. The feasibility of the proposed measurement principle is shown by a morphology analysis between the data acquired by radar and PCG for the dominant heart sounds S1 and S2: The correlation is 82.97 ± 11.15% for 5274 used occurrences of S1 and 80.72 ± 12.16% for 5277 used occurrences of S2. The performance of the proposed detection method is evaluated by comparing the F-scores for radar and PCG-based heart sound detection with ECG as reference: Achieving an F1 value of 92.22 ± 2.07%, the radar system approximates the score of 94.15 ± 1.61% for the PCG. The accuracy regarding the detection timing of heartbeat occurrences is analysed by means of the root-mean-square error: In comparison to the ATM algorithm (144.9 ms) and the PCG-based variant (59.4 ms), the proposed method has the lowest error value (44.2 ms). Based on these results, utilising the detected heart sounds considerably improves radar-based heartbeat monitoring, while the achieved performance is also competitive to phonocardiography.

    abstract = {Vital sign monitoring systems play a crucial role in the medical environment. Patients in palliative and intensive care can especially benefit from continuous observation by detecting sudden changes in health status allowing the medical staff to promptly provide intensified symptom amelioration at the end-of-life. However, machine based monitoring like electrocardiography requires the patient being permanently wired to the device. This circumstance severely restricts the independence and mobility of the patient, leading to a decrease in the quality of life. For this reason, palliative care stations currently usually avoid continuous monitoring. After a comprehensive literature survey and background research, this paper presents a novel approach by using a single radar system to perform continuous and above all contactless monitoring of respiration and heartbeat. A continuous wave radar using the Six-Port technology is introduced and its feasibility, performance and real-time capability are validated in long-term measurements on different test persons. In comparison to gold standard reference devices a correlation of 97.6% was achieved.},

Large body motions or even small distance deviations, such as movement of the chest induced by heartbeat or breathing, are distinguishable from the measured noise of an unoccupied bed. For classifcation two features are calculated based on windowed I and Q data. Performance is evaluated by varying window sizes from 0.2 ... 1.5 s for feature calculation and training of the SVM classifer. In the resting scenario an accuracy of 99.2% and F1-score of 99.1% with windows of 0.2 s is achieved.
