摘要 分析了联合广义分数傅里叶变换相关器相关峰的特性,得到通过改变广义分数傅里叶变换的系统参量可以提高广义分数相关峰性能的结论.进行了数值模拟和光学实验,并根据两者的结果对四个相关峰的性能指标相关峰强度最大值、峰能比、识别能力、信噪比进行了比较分析,说明只要适当控制系统参量,联合广义分数傅里叶变换相关器比联合分数傅里叶变换相关器具有更好的相关性能,有助于提高光学相关器识别的准确率. The performance of the extended fractional correlation peak （EFCP） was analyzed. Numerical simulations and optical experiments with different EFRT parameters were performed. Using four performance criteria, correlation output peak intensity, peak-to-correlation energy ratio, discriminability ratio, and signal-to-noise ratio were analyzed. The results demonstrate that the JEFRTC＇s performance can be better than the JFRTC＇s by adjusting some EFRT parameters.
