Data Reconstruction based on Non-uniformly Sampled Signal

The multireceiver sampling in space domain is equivalent to multichannel sampling in time domain. In general, the multichannel sampling often suffers from non-uniform sampling, which would lead to ghost targets. In order to solve this problem, the uniform data should be reconstructed by using non-uniform sampling signal. In this paper, the filter bank is first introduced, and then exploited to recover the uniform data. After that, the simulations are conducted. The results show that the uniform data can be well recovered based on the non-uniform sampling data. The autocorrelation functions indicate that the recovered signal can well suppress the ghost targets.
