提出了一种利用光梳实现密集波分复用微波信道化接收机的光子学方法。在该方法中，使用两个级联的马赫-曾德尔调制器产生具有11条梳线的平坦光梳。利用光梳、具有周期传递函数的光学标准具、波分复用器（WDM）和光电探测器阵列，实现了对多频微波信号的频率分析。系统进行了数值研究。实现了多频信号的频率测量，测量范围为0.5-11.5，精度为±0.5GHz。通过调整梳状线间距和标准具的峰值位置实现了系统的可重构性。文中还讨论了采用优化周期滤波器提高系统动态范围的问题。
A photonic approach to implementing a microwave channelized receiver based on dense wavelength division multiplexing using an optical comb is proposed. In the approach, a flat optical comb with 11 comb lines is generated using two cascaded Mach-Zehnder modulators. Frequency analysis of a microwave signal with multiple-frequency components is realized by using the optical comb together with an optical etalon with a periodic transfer function, a wavelength division multiplexer (WDM) and a photodetector array. The system is investigated numerically. Frequency measurement of a multi-frequency signal with a measurement range from 0.5-11.5 with an accuracy of ±0.5GHz is achieved. The reconfigurability of the system realized by tuning the comb-line spacing and the peak positions of the etalon is also evaluated. The improvement of the dynamic range of the system using an optimized periodic filter is also discussed.
