Book excerpt: There is a need to detect vital signs of human (e.g., the respiration and heart-beat rate) with noncontact method in a number of applications such as search and rescue operation (e.g. earthquakes, fire), health monitoring of the elderly, performance monitoring of athletes Ultra-wideband radar system can be utilized for noncontact vital signs monitoring and tracking of various human activities of more than one subject. Therefore, a stepped-frequency continuous wave radar (SFCW) system with wideband performance is designed and implemented for Vital signs detection and fall events monitoring. The design of the SFCW radar system is firstly developed using off-the-shelf discrete components. Later, the system is implemented using surface mount components to make it portable with low cost. The measurement result is proved to be accurate for both heart rate and respiration rate detection within ±5% when compared with contact measurements. Furthermore, an electromagnetic model has been developed using a multi-layer dielectric model of the human subject to validate the experimental results. The agreement between measured and simulated results is good for distances up to 2 m and at various subjects' orientations with respect to the radar, even in the presence of more than one subject. The compressive sensing (CS) technique is utilized to reduce the size of the acquired data to levels significantly below the Nyquist threshold. In our demonstration, we use phase information contained in the obtained complex high-resolution range profile (HRRP) to derive the motion characteristics of the human. The obtained data has been successfully utilized for non-contact walk, fall and limping detection and healthcare monitoring. The effectiveness of the proposed method is validated using measured results.

Download or read book Design and Development of Stepped Frequency Continuous Wave and FIFO Noise Radar Sensors for Tracking Moving Ground Vehicles written by Teoman Emre Ustun and published by . This book was released on 2001 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The design and development of two different, small, low-cost, low-power radar sensors are presented in this thesis. A stepped frequency continuous wave (SFCW) radar and a first-in-first-out (FIFO) noise radar are designed and implemented to detect and track moving ground vehicles through weedy foliage. This is done with both the target and radar close to the ground. In addition, the operating principles of both radar systems are presented from a mathematical point of view. The target tracking is performed both in range and azimuth. A monopulse technique is used to track targets in azimuth. Each of these radar sensors is implemented using state-of-the-art, surface mount, and commercial-off-the-shelf (COTS) components. The operating band of the SFCW radar is chosen as 3.0 - 3.6 GHz. The design procedure of a new concept radar, called FIFO noise radar is presented in detail. The FIFO noise radar is operated at a center frequency of 3.3 GHz with a bandwidth of 100 MHz. The performance characteristics of both radar sensors are presented. It is shown that the SFCW radar is a feasible radar sensor for tracking moving ground targets in both range and azimuth, because of its high amplitude sensitivity and stability. The range tracking capabilities of the FIFO noise radar sensor are also presented.

Available in PDF, EPUB and Kindle. Book excerpt: The intent of this project was to design and simulate a frequency modulated continuous wave (FM-CW) radar system capable of making target range and velocity measurements. MATLAB was used to model each component of the FM-CW radar system and simulate transmit and receive signal behavior, channel effects, and target radar cross section (RCS) characteristics. A top-down approach to the design of the FM-CW radar system was presented beginning with an overview of theory and architecture followed by a detailed explanation of each component in the signal path. Key interactions between components were discussed as well as potential differences between real world components and their simulated counterparts. An overview of the signal processing techniques and software architecture required to make target range and velocity measurements was also presented and implemented. An overall FM-CW radar system simulation was implemented in MATLAB including simulated channel effects and targets. The simulation was run so that resultant target range and velocity measurements were obtained and radar system performance and simulation fidelity were evaluated and presented.

Book excerpt: Radarsensoren detektieren Objekte innerhalb eines Beobachtungsbereichs und messen die Entfernungen und Radialgeschwindigkeiten dieser sogenannten Ziele relativ zum Ort des Radars. Für die gleichzeitige, hochgenaue und eindeutige Messung von Entfernung und Radialgeschwindigkeit, auch in Mehrzielsituationen ist der Sendesignalentwurf ausschlaggebend. In der vorliegenden Arbeit werden zunächst die bereits etablierten Sendesignale für Dauerstrichradare erörtert, bevor auf dieser Basis Weiterentwicklungen dieser Sendesignale beschrieben und analysiert werden. Zusätzlich werden Detektionsverfahren beschrieben und für die Verwendung mit den neuen Sendesignalen weiterentwickelt. Radar sensors detect objects, so-called targets, within an observation area and measure range and radial velocity relative to the location of the radar. The simultaneous, highly accurate and unambiguous measurement of range and radial velocity even in multi target situations is a matter of the appropriate waveform design. This thesis describes and analyzes state of the art waveforms for continuous wave radar. Based on these waveforms new approaches and enhancements are presented. In addition to that, detection methods are discussed and improved for the use in combination with the new radar waveforms.
