Thus, for any scattering problem, the col-umns of V and U define our scattering channels, within which our input and output waves can be decomposed, as follows: ψ in Vc in, (2a) ψ outi Uc out, (2b) where c in and c out are the vector coefficients of the excitations on these channels as shown in Fig. 1(b). The scattering .

Examine their radar signatures in the form of inverse synthetic aperture radar (ISAR) images. ISAR imaging provides not only radar cross section (RCS), but also maps the dominant scattering in 2-D. Scientific Questions: 1. Will the small size and low reflectivity of the drone body result in a very low RCS? 2.
