Image reconstruction from the 1997 Ipswich data using conjugate-gradient

Abstract

The conjugate gradient algorithm is shown to be effective in reconstructing targets from experimental radar measurements. Enhancement, using the reciprocity relation to complete the scattered data, is also shown. The small number of iterations needed to obtain a satisfying solution (less than 50 iterations), combined with the increasing computation power of new processors (an SGI R10000 needs 30 sec to compute one iteration), make it possible for this algorithm to be used for practical applications.
