N2 - The acquisition of high-resolution radar images usually requires large-bandwidth signals and long data acquisition times, which inevitably leads to large amounts of data. How to reduce the consumption of data processing and increase the speed of data processing is one of the important contents in the field of Synthetic Aperture Radar (SAR). And wide coverage requirements will inevitably have an impact on the resolution of SAR. Sparse sampling and Compression Sensing (CS) technology can alleviate these problems to some extent. In this paper, the method of sparse sampling and CS is further studied. Then a new kind of SAR signal sparse sampling method based on co-prime arrays is introduced. The non-uniform sparse sampling feature of the uneven array is used to reduce the sampling requirement of the SAR echo signal. The effectiveness of above method is also analyzed at last.
