Embodiment
[0125]This embodiment proposes an ultra-low sidelobe synthetic aperture radar imaging method based on a complete complementary sequence, where the parameters involved in the imaging process are shown in Table 1.
[0126] Table 1 Example parameters
[0127]
[0128] This embodiment specifically includes the following steps:
[0129] Step 1: Divide the echo data C based on the complete complementary sequence signal waveform into the echo data C obtained by separately using sequence A and sequence B as radar transmission signals 1 and C 2 ;
[0130] C 1 and C 2 is also a two-dimensional complex array. According to formulas (3) and (4), C can be obtained 1 and C 2 .
[0131] Step 2: range pulse compression processing based on matched filtering;
[0132] Using the two complementary code sequence signals of the complete complementary sequence as reference signals, the echo data C of sequence A and sequence B are respectively 1 and C 2 Perform distance matching filterin...
