Range profiles have been used for the purpose of target identification. A new R‐SAR (reverse‐synthetic aperture radar) algorithm is introduced here for the purpose of suppressing the clutters contained in the range profiles. The clutter‐suppressed range profiles, called image‐based range profiles, provide a significantly improved target recognition performance when compared with conventional systems which use raw range profiles contaminated with clutters. The experimental results with three kinds of model targets show that there is an improvement of about 15–56% in the matching score, and this will lead to a considerable improvement in the recognition rate for any target recognition algorithm. © 2001 John Wiley & Sons, Inc.
