Opportunities of applying of generalized complementary signals in synthetic aperture radars

The most important feature of the autocorrelation function (ACF) of the synthetic aperture radar (SAR) signals is the level of their side lobes, because they determine the dynamic diapason of the image and the possibility to discover small objects. At present in the radars widely applied are signals with linear frequency modulation, but they have some disadvantages like as relatively high level of side lobes of the ACF and complexity of the generating and processing hardware. In contrast, the signals with inner pulse phase manipulation (PM) have found recently large application in wireless communications and as a result, the PM signal generating and processing hardware is drastically improved. With regard to this feature of PM signals, our paper aims to suggest a mathematical method for synthesis of a class of PM signals, which ACF have close-to-zero level of the side lobes and to study its application in SARs.
