Abstract
Electrical and electronic engineering is moving forward to improve the quality of life of people. In particular, electromagnetic sensors can be used to detect and localize persons indoors and outdoors. The range of applications is vast, going from the fall detection of elderly people at home to the monitoring of vital signs for healthcare applications, the detection of trapped persons after avalanches or earthquakes, and human-aware localization gaming.Radars have emerged as interesting noncontact devices which can contribute to the implementation of these ideas. In particular, coherent linear-frequency-modulated continuous-wave (LFMCW) radars are short-range devices with unique features. This chapter reviews these advantages in terms of architecture, cost, signal processing issues, resolution, accuracy, phase-based precision, clutter isolation, and so forth.Simulations and experimental data are also provided to confirm the suitability of LFMCW radar prototypes to human-aware localization applications.
