The high computational load associated with multidimensional high-reso
lution algorithms is overcome by using only 1D LP techniques. The 3D b
ackscattered field is approximated by three 1D AR models that are solv
ed in succession for the down-range, horizontal cross-range, and verti
cal cross-range positions of the scattering centers of a target. (C) 1
