Abstract

Radar-communication integration is one of the research hotspots in recent years

which can simultaneously realize target detection and data transmission in a single system. In this paper

a simple and compact radar-communication integration scheme based on the optical injection of a semiconductor laser is proposed. The coherence between the master and slave lasers is improved by locking the slave laser with the

-order modulated optical sideband of the injected phase-modulated optical signal. By changing the period-one oscillation frequency and the injected optical signal

an amplitude shift-keying linearly frequency-modulated (ASK-LFM) signal with tunable operating frequency band and frequency multiplication factor is generated. The radar and communication functions of the integrated system based on the generated signal are verified through experiments and simulations. The experimental results show that for the ASK-LFM signal with a bandwidth of 1 GHz

the measurement error of the target range is better than 3.2 cm

the imaging results of the three targets are identifiable

and the correct transmission of communication data is achieved at the same time.
