Radar-Embedded Communication （REC） is a covert communication method that uses Radio Frequency （RF） tags or transponders to generate communication signals， and hides the communication signals in the radar backscatter echo with the radar backscatter echo signal as the background. To meet the requirements for simple， compact and portable RF tags， a low-complexity REC communication waveform generation algorithm is proposed， which can greatly reduce the computational pressure of the RF tag transponder. Simulation analysis shows that the proposed algorithm can greatly reduce the processing gain of the interception receiver by adjusting waveform parameters， and thus increase the Low Probability of Interception （LPI） performance of the REC waveform without sacrificing the reliability and LPI of the REC waveform.
