摘要：

The minimum-energy-criterion (MEC) algorithm introduces the correlation between frequency points to the reconstruction process and uses the optimization method to realize a good reconstruction of multichannel signals in the nonuniform sampling scenario. However, the reconstruction performance of the MEC algorithm will change with pulse repetition frequency (PRF). In this paper, we proposed an improved minimum-energy-criterion (IMEC) algorithm that sets the appropriate reconstruction bandwidth according to the system requirements, which achieves a more robust reconstruction performance than the MEC algorithm.
