Frequency Dependencies of Target Highlights

Abstract

The objective of this work was to examine the frequency dependencies of target highlights to determine where computational savings could be realized in broadband applications. Significant savings can be achieved by simply separating all frequency-independent calculations from the frequency loop. In some cases, highly accurate approximations will provide additional savings. In other cases, and contingent on the user's fidelity requirements, coarser approximations will yield yet more savings. Separation of frequency-independent factors and accurate approximations should be implemented as soon as feasible. Coarser approximations should be implemented, but their use should be contingent on a tolerance test.
