摘要：
We propose an optoelectronic arbitrary radar waveform generator. It permits to generate predefined electrical waveforms according to radar specifications by driving phase and amplitude distributions of optically carried microwave signals. The control of amplitudes and phases of each radar spectrum frequency component is optically achieved by spatial light modulators (SLM). We present and experimentally demonstrate two ways to achieve the kilohertz high resolution between the frequency components of a radar signal at 7.1 GHz central frequency.
