This paper proposes and demonstrates a novel microwave photonic receiving structure that employs two-stage superheterodyne with ultra-wideband tunable coherent dual optical carriers. This technique enables the down-conversion and despread of high frequency broadband spread spectrum signals, while ensuring ideal suppression of image frequency. The results demonstrate high performance in microwave photonic receiving of the proposed method.
