Development of Stepped-Frequency Continuous-Wave Radar Sensors

This chapter presents the development of two SFCW radar sensors realized in single packages with microwave integrated circuits (MICs) and microwave monolithic integrated circuits (MMICs): a millimeter-wave sensor operating across 29.72-37.7 GHz and a microwave sensor working from 0.6-5.6 GHz. The designs of the transceivers, antennas and signal processing, which form the most important parts of the sensors, are described. The presented information, although concise, is essential and in sufficient details, which enable microwave engineers to build similar microwave and millimeter-wave SFCW radar sensors for various sensing applications.
