Nowadays drones diffusion represents a nonnegligible risk and drone detection systems become a necessity to avoid this danger. In this paper the design of a frequency modulated continuous wave (FMCW) radar is presented. The sensor is based on the Infineon BGT24MTR11 integrated circuit. Transmitting and receiving serial arrays of patch antennas have been suitably designed. For the transmission a single antenna has been used, while a group of four receiving antennas has been employed thus realising a Multiple Input Single Output (MISO) system.

This paper presents the study of a radar system for indoor human localization and vital signs monitoring. The article illustrates different solutions including linear frequency-modulated continuous-wave (FMCW) mode and recently proposed hybrid schemes, combining FMCW and continuous-wave (CW) interferometry modes. A new operating modality based on the use of the phase variations of the demodulated FMCW signal is also proposed.
