Zusammenfassung:	Aspects of the present disclosure are directed to injection locking and related apparatuses. As may be implemented in accordance with one or more embodiments, an apparatus includes a plurality of injection-locking circuits configured to receive an injection signal, each injection-locking circuit including a mixer and a lock-detection circuit. In each of the injection-locking circuits, the lock-detection circuit detects a lock-status relationship between the injection signal and a signal output from the injection-locking circuit. In response to the lock-status relationship indicating an unlocked condition, a phase/magnitude of the injection signal is adjusted. In response to the lock-status relationship indicating a locked condition, transmission of an FM continuous wave (FMCW) chirp signal is facilitated.
