| Abstract: | The influence of the fractional orders of the fractional Fourier transforms on the correlationpeak properties of the fractional correlation (FC) has been analyzed by computer simulation. Theoptimized fractional orders of FC have been given. It is demonstrated that the performances of FC havebeen improved in correlation peak compared with the classical correlation. Therefore the sensitivity ofdetecting target can be enhanced. |
