Abstract
In a frequency-offset self-injection-locked (FOSIL) radar, a first mixer is provided to mix a first oscillation signal of a first injection-locked oscillator (ILO) and a second oscillation signal of a second ILO so as to cancel out the frequency drifts of the first and second oscillation signals. Accordingly, the transmit frequency of the FOSIL radar can remain constant to mitigate the EMI issue.
