Abstract

Multifunctional integration of electronic equipment is a main development trend in the future, wherein the integrated signal generation enables a key part. Therefore, it is of great significance to develop the generation of anti-jamming joint radar-communication (JRC) signal. Here, a photonics-assisted generation scheme of millimeter-wave (MMW) anti-jamming JRC signal is proposed. A large-bandwidth MMW dual-band agile JRC signal is generated based on a photonic MMW up-conversion and frequency permutation techniques. Meanwhile, thanks to the dual-band photonic radar de-chirping combined with coherent fusion method and low-cost communication self-coherent reception, the high resolution radar detection and communication with large amount of information are realized simultaneously. In the photonics-assisted JRC simulation system in W-band, a dual-band agile stepped-linear frequency modulation JRC signal covering 81-93 GHz is generated. Moreover, through a dual-band coherent fusion processing, the dual-band signals occupying with only a bandwidth of 2 GHz are successfully fused into an equivalent ultra-wideband signal with a bandwidth of 12 GHz, enabling a radar ranging with a resolution of 1.26 cm. Using a low-cost self-coherent reception, an anti-jamming wireless communication with factorial 10 is demonstrated, which can achieve up to 21.8 bits quantity of information.
