The focus of this study is on the waveform design of the radar system that shares spectrum with the communication system in multi-path environments. The main challenge comes from combining useful multi-path target echoes received at the radar system while suppressing radar interference to communication users. Specifically, we formulate the waveform design problem as a maximization of the signal-to-noise ratio (SINR) subject to constraints of communication rate and the similarity degree with some standard waveform. The multi-path propagation complicates the expressions of the radar SINR and communication rate, increasing the difficulty of solving the problem. We propose a sub-optimal algorithm based on the successive convex approximation and semi-definite programming methods to solve the problem. Simulation results are provided to demonstrate the effectiveness of the proposed design.
