Abstract

Facing the scarcity of spectrum resources, the spectrum sharing between radar and communication system has attracted a lot of attention in both industrial and academic communities. In this paper, we consider the co-existence of MIMO radar and MISO secure communication systems. In order to improve the secrecy performance, we jointly design the radar waveform and communication beamformer. Specifically, we aim at maximizing the secrecy capacity under the constraints of transmit power, radar waveform, and interference from BS to radar. To deal with the non-convex problem and the coupled variables, we use semidefinite relaxation (SDR) and successive convex approximation (SCA) techniques to solve the problem. Numerical results show that the proposed joint design algorithm can improve the secrecy performance of communication system signficantly.
