Abstract

An improved target extraction algorithm was presented for the target extraction problem of linear modulated stepped frequency signal one-dimension imaging. Based on the idea that the maximum peak of the target echo may lie in any position of the extraction range of its low range resolution cell, several high resolution range profiles (HRRP) were extracted. By extracting the scatters of the target in each HRRP, one can accumulate the energy of all the scatters. The HRRP in which the scatters of the target have the most energy will be chosen as the HRRP of the target. The validity of this method is proved by processing field measured data. It is shown that the performance is better than inverse discard method.
