Performance Analysis of Fractional-Order Filtering in a Joint Fractional Fourier-Transform Correlator

通过理论分析和计算机仿真研究了联合分数傅里叶变换相关器经过分数级滤波处理后的相关特性.结果表明处理后的联合分数傅里叶变换相关器的相关性能与未处理的联合分数傅里叶变换相关器的相关性能相比有了较大的改善,提高了目标探测的灵敏性.

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.
