ABSTRACT This paper presents a portable radar sensor developed in the Universidad Politecnica de Madrid. The system transmits a Linear Frequency Modulated Continuous Wave (LFM-CW) with two-antenna configuration for transmission and reception. The radar transmits at millimeter-wave band with a maximum bandwidth of 2 GHz and a transmitted power of 1 W. The system is modular, compact and lightweight. The sensor allows range intervals tuning and sampling the received signals with a constant rate. By this, it is particularly attractive for portable applications. Finally, the system performance has been tested in a traffic surveillance experiment.

    ABSTRACT: This paper focuses on the exploitation of linear-frequency-modulated continuous-wave (LFMCW) radars for noncontact range tracking of vital signs, e.g., respiration. Such short-range system combines hardware simplicity and tracking precision, thus outperforming other remote-sensing approaches in the addressed biomedical scenario. A rigorous mathematical analysis of the operating principle of the LFMCW radar in the context of vital-sign monitoring, which includes the explanation of key aspects for the maintenance of coherence, is detailed. A precise phase-based range-tracking algorithm is also presented. Exhaustive simulations are carried out to confirm the suitability and robustness against clutter, noise, and multiple scatterers of the proposed radar architecture, which is subsequently implemented at the prototype level. Moreover, live data from real experiments associated to a metal plate and breathing subjects are obtained and studied.

    ABSTRACT: Radars are among the best exponents of radio-frequency (RF)/microwave devices for remote sensing [1], [2]. Long-range radars have demonstrated outstanding potential not only for defense/security environments, such as the detection, location, and tracking of targets, but also on a plurality of civilian scenarios, such as meteorological/weather measurement tasks, imaging of the Earth's surface through synthetic aperture radar (SAR) techniques, monitoring of animal migrations, and many others [3]-[7].

    ABSTRACT: This paper explores the field of multiband radar as a further step in the research into advanced remote-sensing systems with enhanced capabilities. Specifically, a deramping-based multifrequency radar concept is addressed. Several multiband radar architectures are discussed and compared in terms of performances and hardware complexity. For the minimum-hardware multifrequency radar configuration, a proper design for its multiband waveform is suggested which enables the exploitation of all the operation features expected for such a system. Simulated inverse-synthetic-aperture data for a linear-frequency-modulated continuous-wave (LFMCW) dual-frequency radar emphasizes the usefulness and limitations of this multiband radar approach.
