RESPONSE TO ANALYSIS AND COMPARISON OF RECENT RESONANCE SCATTERING FORMULATIONS BY CHOI,M.S. ET-AL. WITH EARLIER, TRADITIONAL RST WORK [J. ACOUST. SOC. AM. 104, 1720 (1998)]

In the letter by Gaunaurd, there were some comments on recent resonanc e scattering formulations by the author and his colleagues. Replies to the comments are made here. To clarify the discussion, brief reviews on the recent formulations and more traditional ones are included. It is shown that the recent approaches are based on much more robust phys ical concepts and approximations than the traditional ones, so that th ey are sufficient to be presented as novel tools for target identifica tion purposes.
