    摘要: A homodyne radar system includes an oscillator, an antenna, a low noise amplifier, a mixing subsystem and a directional coupler. The oscillator is configured to generate a transmit signal and a local oscillator signal. The antenna is configured to transmit the transmit signal and to receive a receive signal. The low noise amplifier is configured to amplify the receive signal. The mixing subsystem is configured to receive and mix the transmit signal and the receive signal to produce an output signal. The directional coupler is coupled to the antenna, the oscillator, the low noise amplifier and the mixing subsystem. The directional coupler is connected and configured to provide a low-loss transmission path from the antenna to the low noise amplifier and a high loss transmission path from the oscillator to the antenna.

    摘要: In various embodiments, systems and methods for automatically tuning an antenna to a desired frequency utilize a tuning detection element that sends or receives a signal in accordance with one mode of the antenna and that is separated from the antenna by a gap and outside of a signal path of the antenna. In various system implementations, a processor communicates with the tuning detection element and antenna and monitors the amplitude of a signal transmitted to or from the tuning detection element. A resonant frequency of the antenna may be tuned to the desired frequency by a tuning element.
