Abstract

This paper proposes a channelized receiver based on microwave photonic, the system generated two coherent optical frequency comb with different free spectral ranges. By adjusting carrier frequency, a different frequency interval is formed between the local frequency comb and the optical comb modulating the signal to be measured. After the two optical combs pass through the optical demultiplexer respectively, the corresponding channel is beat frequency and the heterodyne detection is realized by converting the signal to intermediate frequency.The scheme proposed in this paper realizes the measurement frequency range of 2GHz~18GHz, has the instantaneous bandwidth of more than 7GHz, and the average error is less than 50MHz
