| Abstract: | The correlation properties of fractional-order filtering in a joint fractional Fourier-transform correlator is discussed. The result demonstrates that the correlation performances of processed joint fractional Fourier-transform correlator have been improved compared with the unprocessed joint fractional Fourier-transform correlator, and the sensitivity of detecting target has also been enhanced. |
