This chapter has provided an overview of the radar fundamentals, system design, prototyping, and signal processing of FMCW radars for micro-Doppler detection. The design principles of each part of an FMCW radar, including the radar transceiver, link budget, antenna design, etc., have been introduced and discussed. Besides the hardware design, range-Doppler and micro-Doppler effects in radar signal processing have also been discussed in detail. Finally, a brief introduction has been given in this chapter to cover the emerging applications for range-Doppler and micro-Doppler effects.
