“…With the echoed waveforms from the subject being received, the coherent dechirping is firstly performed to the signal. Then the de-chirped signal, which is coherent to the RF signal, is amplified by an intermediate frequency (IF) amplifier and processed by the ITPA algorithm to realize localization on the subjects, monitoring on various kinds of vital signs, and detection on the falling movements [104], [117].…”

“…thus, the detection efficiency is enhanced. Compare to the MUSIC [2], where the direction of arrival (DoA) is ensured at the receiver side, in our method, the target direction is selected by the initiatively accurate beam-steering of the phased-array radar sensor [117].…”

“…A typical FMCW radar sensing experimental setup for precise indoor localization and versatile life activity monitoring is illustrated in Fig. 2 [106], [114]- [117]. It is clearly demonstrated that the FMCW radar can achieve localization on subjects while it is hard for single-frequency CW radars.…”

SummaryThe research and development on solid‐state source generators have been making progress on chip, aiming to generate low noise, high output power, and high DC‐to‐RF energy efficiency in the millimeter‐wave (mmW) and terahertz (THz) domains. In particular, their full integration in silicon technologies, such as advanced complementary‐metal‐oxide‐semiconductor processes, has motivated the design of low cost, high performance, and miniature integrated circuits (ICs). This manuscript focuses on providing a general overview of recent progress on solid‐state signal source operating beyond 60 GHz till the THz region, from the perspective of operating principle, design metrics, state‐of‐the‐art performance, testing results, and their applications in emerging mmW/THz systems. Finally, with the use of fully integrated source generators, several design arts are highlighted to showcase the recent advances of ICs toward millimeter‐wave and THz radiation, imaging, coupled oscillator network (CON), and communication. Potential future research directions enabled by mmW/THz signal sources will be envisioned.
