Abstract: Accurate displacement measurement with Doppler radar necessitates the incorporation of phase demodulation techniques. However, these techniques are prone to phase ambiguity, as target ...
Abstract: High-frequency signal injection method is a common control strategy for interior permanent magnet synchronous motor (IPMSM) drives at zero and low speeds. A reasonable demodulation method is ...
Block diagram of demodulator section: As you can see, I'm using a Costas Loop with a PI (Proportional-Integrator controller) to control the local oscillator The screenshot at the top shows an example ...
