We examine the moving range-spread target in distributed multi-input multi-output (MIMO) radar. More precisely, a knowledge-aided (KA) model for nonhomogenous disturbance is proposed. We model the covariance matrices for different transmit-receive (Tx-Rx) pairs as random matrices, which share the same matrix structure but with different power levels for the non-homogeneous clutter powers across different...
This paper deals with the problem of detecting a moving range-spread target in distributed MIMO radar. A new knowledge-aided (KA) model that takes into account the nonhomogenous characteristics of the disturbance (clutter and noise) in distributed MIMO radar is proposed. Specifically, the disturbance covariance matrices corresponding to different transmit-receive (Tx-Rx) pairs are modeled as random...
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...
In this paper, we consider parameter estimation for moving target detection using a distributed MIMO radar, where the multi-static transmit-receive configuration causes non-homogeneous clutter. Specifically, the clutter power for the same resolution cell may vary significantly from one transmit-receive pair to another, due to azimuth-selective backscattering. Moreover, the clutter power may also vary...
