Abstract
An improved range profile extraction algorithm based on multi-scatters was proposed to solve the problem of scatters' amplitude loss during the complicated target's range profile extraction in the stepped frequency radar. First, according to the target's highest peak of scatters, a reference range profile was extracted based on the inverse discard method. Then the target's multiple scatters were extracted, and the sets of extraction starting points were obtained based on each scatter's peak in the descending order of amplitude. Then the intersection among these sets was successively calculated as the ideal starting point. This algorithm can extract as many scatters' peak amplitude as possible, and the range measurement of each scatter is more accurate. Simulation results and field measured data demonstrate the advantages of the proposed method over the others.
