Waveform Design and Processing for Joint Detection and Communication Based on MIMO Sonar Systems

Recently, the concept of joint detection and communication (JDC) has drawn considerable attention in radar and sonar systems. In this paper, we propose a waveform design and processing method for the JDC based on multi-input multi-output sonar systems (JDC-MIMO). Orthogonal frequency division multiplexing (OFDM) signals are designed to perform target detection and information transmission simultaneously. Furthermore, a joint pilot design scheme is proposed for the JDC-MIMO system, which can significantly improve the spectrum utilization. Numerical simulation results show that the proposed method has satisfactory performance in both detection and communication.
