Direction modulation (DM) is a physical layer security (PLS) technology that has attracted extensive research. In this paper, a symbol-level design for radar communication integration systems is proposed based on DM. In the radar direction, the performance of target estimation is ensured by minimizing the Cramér-Rao bound (CRB) of sensing, while maintaining the desired constellation patterns in the communication directions and meeting the mismatch threshold with the random signal in the undesired directions, disrupting the constellation patterns. The numerical results demonstrate that the proposed method has an extremely low CRB in the radar direction and low bit error rate (BER) levels in the communication directions.
