Abstract
A digital beamforming synthetic aperture radar (SAR) mixes a first analog signal to generate a frequency-shifted first signal having a first spectral band, mixes a second analog signal to generate a frequency-shifted second signal having a second spectral band, positioned at a defined frequency offset from the first spectral band, and positioned non-overlapping relation with the first spectral band, combines the first and second frequency-shifted signals to generate a combined analog receive signal, and band-pass samples the combined analog receive signal to generate a digital baseband signal representative of the first and second analog signals. The SAR may mix the second analog signal to position the second spectral band in the Nyquist bandwidth, and in non-overlapping relationship with the first spectral band. Mixing may include down converting the analog signal.
