Self injection locking
Injection locking and injection pulling are the frequency effects that can occur when a harmonic oscillator is disturbed by a second oscillator operating at a nearby frequency. When the coupling is strong enough and the frequencies near enough, the second oscillator can capture the first oscillator, causing it to have essentially identical frequency as the second. This is injection locking. When the second oscillator merely disturbs the first but does not capture it, the effect is … WebMay 14, 2024 · Impact Statement: Take-Home Messages •The self-injection-locked (SIL) radar sensor system can be used in healthcare, such as for noncontact vital sign and motion detection, without the need for a complex system. •SIL radar sensor systems have greater sensitivity, better signal-to-noise ratio, and greater clutter immunity than conventional …
