| Abstract: | A new method of non-uniformly sampling signal recovering is given based on reduced frac- tional Fourier transform （RFRFF）. The algorithm and the formula of spectral reconstruction is de- duced by continuous frequency spectrum unbiased estimator. And this algorithm is tested and verified which is stable, effective and feasible with the MATLAB, which is used in the RFRFT domain for the linear FM signal （LFM）. |
