Techniques and methods for frequency division multiplexed digital beamforming

摘要

A system includes a first low noise amplifier, a second low noise amplifier, a local analog oscillator signal, a signal splitter, a mixer, a mixer, an analog to digital converter and a digital channelizer. The first low noise amplifier outputs a first amplified analog signal based on a received analog antenna signal at a time t₀. The second low noise amplifier outputs a second amplified analog signal based on the received analog antenna signal at a time t₁. The local analog oscillator signal outputs a local analog oscillator signal. The signal splitter outputs a split analog oscillator signal and a split analog oscillator signal. The mixer outputs a first mixed signal. The mixer outputs a second mixed signal. The analog to digital converter outputs a combined digital signal. The digital channelizer outputs a received signal based on the combined digital signal.
