abstract = {To resolve the problem of high hardware consumption and difficulty in engineering implementation in digital Stretch processing with large decimation multiples, a new method based on cascading segmented FFT (fast Fourier transform) processing was proposed. The data sequence after digital mixing is cascading segmented and reorganized, and then the digital Stretch processing was realized by using the less points FFT operation. The experimental results based on the measured data prove the effectiveness of the presented strategy. The resource consumption analysis demonstrates that the proposed method can implement digital Stretch more hardware-efficiently compared with the conventional method.}
