The Shift and Scale Invariant Fourier-Mellin Transform for Radar Applications 14 OCT 1980 55 pages
Authors:  Lyle H. Johnson; MASSACHUSETTS INST OF TECH LEXINGTON LINCOLN LAB
The full text of this report is available for sale.Automatic classification of targets viewed by radar is complicated by variations in target aspect relative to the radar line-of-sight (RLOS). This report investigates the possibility of reducing the effects of target aspect by using the scale invariance of the Mellin transform. The properties of the Mellin transform are developed in analogy with the Fourier transform and illustrated using simple test functions and digitally implemented transforms. Simulated radar ship profiles demonstrate ...
