Analyzing and improving MIMO radar detection performance in the presence of cybersecurity attacks

As a complicated distributed system, distributed MIMO radars are vulnerable to cybersecurity attacks against its three key components: the transmitters, the receivers, and the communication links that connect them and the fusion center. In this paper, we investigate the impact of cybersecurity attacks on detection performance of a distributed MIMO radar. We show that the detection performance degrades significantly if the MIMO radar is not aware of the attacks. To mitigate the attacks, we develop robust detection schemes which can greatly improve detection performance when the radar is under attack.
