A novel approach to photonic generation of phase-coded microwave signals based on optical pulse shaping and time delay is proposed. In the proposed approach, an optical short pulse train is inserted with a specified amount of time-delay to certain pulses, and then converted into super-Gaussian microwave pulses based on the optical pulse shaping technique. By properly adjusting the time-delay, phased-coded microwave signals with a desired code pattern can be generated. A model to describe the signal generation is developed, and the generations of phase-coded microwave signals with frequencies up to 50 GHz are demonstrated.
