Abstract

Recent introductions of low-cost high-performance devices have finally made feasible the implementation of ''under-sampling'' techniques indifferent application areas. A significant example is represented by Doppler analysis, which typically involves the inspection of narrowband spectra around an RF carrier. This letter describes the implementation of an aliasing-free CW ultrasound Doppler system employing a ''single'' under-sampling channel, in place of the two ''quadrature'' sampling channels already proposed by other authors. Implications in terms of clutter rejection are also discussed.
