Abstract:

According to radar target' s width feature , an inverse Chirp-z transformation method was put forward for the target' s detection window .It aimed to obtain high precision range image via increasing sampling resolution . Compared with traditional inverse Fourier transform method , which used zeros padding method , at the same condition of sampling resolution , the method proposed could decrease the calculation load .Simulation corresponded with theoretical analysis , and the results proved it was effective.

Key words: pulse stepped frequency radar, pulse compression, inverse Fourier transform, inverse Chirp-z transform
