Query: Secure Radar-Communication Systems with Malicious Targets: Integrating
  Radar, Communications and Jamming Functionalities   This paper studies the physical layer security in a
multiple-input-multiple-output (MIMO) dual-functional radar-communication
(DFRC) system, which communicates with downlink cellular users and tracks radar
targets simultaneously. Here, the radar targets are considered as potential
eavesdroppers which might eavesdrop the information from the communication
transmitter to legitimate users. To ensure the transmission secrecy, we employ
artificial noise (AN) at the transmitter and formulate optimization problems by
minimizing the signal-to-interference-plus-noise ratio (SINR) received at radar
targets, while guaranteeing the SINR requirement at legitimate users. We first
consider the ideal case where both the target angle and the channel state
information (CSI) are precisely known. The scenario is further extended to more
general cases with target location uncertainty and CSI errors, where we propose
robust optimization approaches to guarantee the worst-case performances.
Accordingly, the computational complexity is analyzed for each proposed method.
Our numerical results show the feasibility of the algorithms with the existence
of instantaneous and statistical CSI error. In addition, the secrecy rate of
secure DFRC system grows with the increasing angular interval of location
uncertainty.
