We propose an arbitrary waveform microwave pulse generation system based on tunable optoelectronic oscillator (TOEO) structure and a dual-drive Mach–Zehnder modulator (DDMZM).

The tunable carrier frequency range can be as large as tens of GHz.

The phase of the generated microwave signal can be tuned in the range of −180° to 180°.

The proposed scheme can realize the integration of frequency tuning, phase tuning, pulse modulation and radar transmitted waveform generation in the optical domain, which provides a guarantee of transmitting high-quality microwave signal in radar systems.
