Abstract

A simple photonic approach for the multiband phase-coded microwave generation based on a dual-drive Mach-Zehnder modulator (DDMZM) is proposed. By injecting the 5-bit barker code sequence to the bias of DDMZM, the binary phase-coded microwave signal for multiband radar application is generated. A proof-of-concept experiment is performed. The generation of phase-coded signals tuning from 1 to 9 GHz with 1 to 20 Mbit/s coding rates is verified.
