An imaging method using the Doppler effect is proposed in this
paper. An object is illuminated by a sinusoidal wave from a linearly moving
transducer. The frequency components of the reflected wave can be considered
to be projections along lines at specified corresponding angles
from the transducer. One can reconstruct images by applying conventional
CT (computerized tomography) algorithms to the projections thus obtained.
The theory is derived for coherent and incoherent processing.
Theoretical results are confirmed by numerical simulations. Experimental
results show that coherent Doppler tomography is much higher in resolution
but more noisy than incoherent Doppler tomography.
