摘要: A digital phased array antenna comprises a plurality of antenna elements, each element receiving an incoming signal. An analog-to-digital converter is coupled to at least one of the antenna elements to convert the incoming signal to a multi-bit digital signal. A demodulator or de-ramp circuit is coupled to the analog-to-digital converter to reduce the bandwidth of the multi-bit signal.

摘要: A waveform generator digitally synthesizes a waveform having a plurality of successive portions that can each be as short as one mono-cycle of the waveform, or a part of one mono-cycle. The waveform generator changes at least one of a frequency, a phase and an amplitude of the waveform between each successive pair of the portions thereof. A method includes digitally synthesizing a waveform having a plurality of successive portions that can each be as short as one mono-cycle of the waveform, or a part of one mono-cycle, including changing at least one of a frequency, a phase and an amplitude of the waveform between each successive pair of the portions thereof.
