| Popis: | The paper presents a brief overview of different types of signals for synthetic aperture radar (SAR). The best chosen signal should provide a minimum peak sidelobes (PSL) level in the range-azimuth plane. This paper gives numerical method for unimodular sequences design with low PSL level of AACF. The results of numerical optimization for constructing of unimodular sequences of lengths N =128, N =256 and N =512 with PSL ≈ 1 are shown. It is shown that the synthesized in this paper unimodular signal with good aperiodic autocorrelation properties has a lowest average PSL in the range-azimuth plane. |
