Abstract: Radar-Embedded Communication(REC) is a new type of covert communication method that embeds communication signals in radar backscattered echoes. Compared with the traditional concealed communication method, REC has superior concealment performance, and thus has very broad application prospects in the military and civilian fields. Waveform design has always been a key research goal in REC. To improve communication reliability and anti-interception performance, a REC communication waveform design method is proposed based on Singular Value Decomposition (SVD). This paper presents the algorithm principle of SVD based waveform design, and analyzes the communication reliability, anti-detection performance, anti-interception performance and algorithm complexity of the SVD waveform. The results show that compared to the traditional REC waveform, the SVD waveform has better communication reliability, Low Probability of Detection (LPD) and Low Probability of Intercept (LPI), and does not cause a significant increase of algorithm complexity.
