Abstract:
|
The inverse scattering problem concerning the determination of the joint time-delay
Doppler-scale reflectivity density characterizing continuous target environments is addressed by recourse to the generalized frame theory. A reconstruction formula,
involving the echoes of a frame of outgoing signals and its corresponding reciprocal
frame, is developed. A ‘‘realistic’’ situation with respect to the transmission of
a finite number of signals is further considered. In such a case, our reconstruction formula is shown to yield the orthogonal projection of the reflectivity density onto a subspace generated by the transmitted signals. |
