Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A homodyne radar system, comprising: an oscillator configured to generate a transmit signal; an antenna configured to transmit the transmit signal and to receive a receive signal; a low noise amplifier configured to amplify the received signal to provide an amplified signal; a mixing subsystem configured to receive and mix the transmit signal and the amplified signal to produce an output signal; and a directional coupler coupled to the antenna, the o…
