Abstract
By changing frequencies of an oscillation signal and an injection signal, a frequency-converted self-injection-locked radar has an oscillation frequency different to a frequency of a transmitted signal from a transceiver antenna element such that the frequency-converted self-injection-locked radar with high sensitivity and penetration or with high sensitivity d low cost is achieved.
Claims11
A frequency-converted self-injection-locked radar, comprising:
- a self-injection-locked oscillator (SILO);
- a frequency converter electrically connected to the SILO;
- a transceiver antenna element electrically connected to the frequency converter;
- and
- a demodulator electrically connected to the SILO;
- wherein the SILO is configured to generate an oscillation signal, the frequency converter is configured to receive the oscillation signal and convert a center frequency of the oscillation signal, the transceiver antenna element is configured to receive the converted oscillation signal, transmit the converted oscillation signal as a transmitted signal to an object and receive a reflected signal as an injection signal from the object, the frequency converter is configured to receive the injection signal and convert a center frequency of the injection signal, the converted injection signal is configured to be injected into the SILO to lock the SILO in a self-injection-locked state, and the demodulator is configured to receive and demodulate the oscillation signal.
