Title: Innovations of Shiang-Hwua Yu in Radar Technology

Introduction: Shiang-Hwua Yu is a prominent inventor based in Kaohsiung, Taiwan. He has made significant contributions to the field of radar technology, holding 2 patents that showcase his innovative approach to self-injection-locked radar systems. His work is characterized by a blend of digital technology and advanced signal processing techniques.

Latest Patents: One of his latest patents is the "Self-injection-locked radar with digital demodulator." This invention features a digital self-injection-locked (SIL) radar that includes a digital SIL oscillator, a wireless signal transceiver, and a digital frequency demodulator. The digital SIL oscillator generates a digital output signal, which is then converted into a wireless signal for transmission to a target. The system also receives a reflected signal from the target, converting it into a digital injection signal for the SIL oscillator. This innovative design allows the digital SIL oscillator to operate in an SIL state, generating a digital oscillation signal that is demodulated into a digital demodulation signal.

Another notable patent is the "Phase-tracking self-injection-locked radar." This invention comprises an SIL oscillator, a phase-tracking SIL loop, and a frequency-locked loop. The SIL oscillator generates an electrical oscillation signal and receives an electrical injection signal for self-injection locking. The phase-tracking SIL loop maintains a constant phase difference between the electrical oscillation signal and the electrical injection signal, ensuring optimal detection points for the radar system.
