摘要

To overcome the limitation of the phased array (PA), the frequency diverse array (FDA) was introduced that can provide precise scanning in distance and angle domains. Utilizing microwave photonics (MWP), a FDA signal generation method based on dual optical frequency combs (OFCs) is proposed in this paper. The scheme successfully generates a five-channel FDA signal with a center frequency of 8 GHz and a frequency offset of 1 MHz. With a power flatness below 2.5 dB and a spurious suppression ratio exceed 27.2 dB, the method demonstrates ability to generate high-quality FDA signal and realize beam forming and scanning. Additionally, the radiation pattern shows a distinct "S"shape, influenced by distance and angle.
