摘要：
To solve the problem of moving target detection under limited radar resource conditions and complex environments, a radar target detection algorithm based on improved sparse Fourier transform (SFT) is proposed. On the one hand, the first level detection is introduced to suppress the influence of strong clutter on sparsity and frequency estimation; On the other hand, the Doppler frequency of suspected targets is used to construct subspace detectors to avoid losing clutter information in the second detection level. The effectiveness of the method is verified by experiments with measured data.
