摘要
本文通过理论分析和计算机仿真研究了分数傅里叶变换的级次对分数相关峰值特性的影响并优化了分数相关的级次．结果表明分数相关输出在旁辩和峰值宽度方面与传统相关相比有了较大的改善，因而可以提高目标探测的灵敏性．
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.
