Self-injection-locked radar: An advance in continuous-wave technology for emerging radar systems

This paper introduces an innovative continuous-wave (CW) radar technology, called the self-injection-locked (SIL) radar. It can compete with pulse radar technology in resisting clutter and interference, but maintains the advantage of low complexity that is associated with the CW radar. Accordingly, an SIL radar can be implemented at low cost, providing high performance and low power consumption. It therefore has great potential to accelerate the killer application development of portable radars for wireless health and safety services, especially when installed in personal mobile devices.
