Chromatic-dispersion-induced power-fading suppression technique for bandwidth-quadrupling dual-chirp microwave signals over fiber transmission

Abstract

We report a technique to overcome chromatic-dispersion-induced power fading (CDIP) for bandwidth-quadrupling dual-chirp microwave signals over fiber transmission. Normally, dual-chirp microwave signals are generated using double-sideband (DSB) modulation. However, DSB modulation suffers from CDIP significantly. We propose a carrier-frequency shift method to suppress the CDIP based on a dual-polarization dual-parallel Mach–Zehnder modulator. In addition, the bandwidth of the dual-chirp signal can be quadrupled by properly setting the biases of the modulator. The proposed technique is theoretically analyzed and experimentally verified. Our technique is promising for improving the range-Doppler resolution of radars for one-to-multi base stations transmission.
