“…Due to the flexibility and good performance, the selfgrounded antennas have been applied or under investigation to the following areas: i) UWB indoor and through-wall radar with precise ranging and tracking due to the wideband performance, fast time-domain impulse response and the compact size [14]; ii) wideband MIMO systems due to the large coverage, good polarization balance and high diversity gain [8], [15]; iii) stroke diagnosis system due to the good near field aperture distribution [16]; iv) UWB SAR imaging of near field object for industrial process [17], [18]; v) breathing and heartbeat detection [19]. vi) receiving antenna on moving vehicles, such as on boats, trains and cars, because of its good Axial Ratio over large elevation angles and low profile.…”

Abstract-The self-grounded antenna is a new type of compact ultra-wideband antennas with simple geometries. One of the characteristics of this type antenna is its high flexibility: the configuration of the antenna can be arranged in many different ways for different applications. In this paper, we overview the typical arrangements of the self-grounded antennas, and their performance for different applications.

“…The UWB radar is a valuable alternative due to its better performances compared with the Doppler one. In fact, the use of very short pulses (of the order of hundreds of picoseconds) results in a lower interference with other systems, lower cost, and lower power density [10][11][12]. Moreover, the low power density radiated by the radar system allows better satisfying regulation limits settled by safety guidelines [13].…”

In this paper, Principal Component Analysis technique is applied on the signal measured by an ultra wide-band radar to compute the breath and heart rate of volunteers. The measurement set-up is based on an indirect time domain reflectometry technique, using an ultra wide-band antenna in contact with the subject's thorax, at the heart height, and a vector network analyzer. The Principal Component Analysis is applied on the signal reflected by the thorax and the obtained breath frequencies are compared against measures acquired by a piezoelectric belt, a widely used commercial system for respiratory activity monitoring. Breath frequency results show that the proposed approach is suitable for breath activity monitoring. Moreover, the wearable ultra wide-band radar gives also promising results for heart activity frequency detection.

“…Certain systems rely on pre-installed infrastructures (Kuusniemi et al, 2012;Saad and Nakad, 2011;Yu et al, 2012). These can include pseudo-satellite transmitters, Radio Frequency Identification (RFID) markers and Ultra-Wideband (UWB) radars.…”

The algorithm flow of an inertial-based Pedestrian Navigation System (PNS) can be divided into a trajectory-generation stage and trajectory-calibration stage. The Zero-velocity UPdaTe (ZUPT)-aided Extended Kalman Filter (EKF) algorithm is commonly used to resolve the trajectory of a walking person, but it still suffers from long-term drift. Many methods have been developed to suppress these drifts and thus to calibrate the trajectory generated by the previous stage. However, these methods have certain requirements, such as explicit map information or frequent location revisits, which are hard to satisfy in such situations as Search and Rescue (SAR) operations. A new approach is proposed in this paper that requires no explicit presupposition. This approach is based on a particle filter framework, with the weight of particles being adaptively adjusted according to the a priori knowledge of building structures and human behaviours. The distribution of particle weights is designed with awareness of the regular structures of buildings. The time-varying parameter of the distribution is acquired from a Hidden Markov Model (HMM) based on the foregoing odometry, which has a close relation with human behaviour. HMM is trained offline based on samples acquired in advance. Many real-world experiments under various scenarios were performed, and the results indicate good accuracy and robustness of the proposed approach. K E Y WO R D S 1. Inertial-based PNS.2.
