The problem of global positioning system (GPS) spoofing attacks on smart grids endowed with phasor measurement units (PMUs) is addressed, taking into account the dynamical behavior of the states of the system. First, it is shown how GPS spoofing introduces a timing synchronization error in the phasor readings recorded by the PMUs and alters the measurement matrix of the dynamical model. Then, a generalized...
This paper addresses the problem of adaptive multiple-input multiple-output (MIMO) radar detection in heterogeneous environment with compound-Gaussian clutter. The clutter covariances are assumed to be random and different from one transmit/receive pair to another with a priori knowledge about the environment. A two-step strategy is employed to design adaptive detector. Firstly, we obtain the generalized...
In this paper, we derive the Cramér–Rao bound (CRB) for joint target position and velocity estimation using an active or passive distributed radar network under more general, and practically occurring, conditions than assumed in previous work. In particular, the presented results allow nonorthogonal signals, spatially dependent Gaussian reflection coefficients, and spatially dependent Gaussian clutter-plus-noise...
In this paper, two different Cramer-Rao bounds are compared for joint target position and velocity estimation for either active or passive radar. The first bound considers the case where the target has been previously detected in a given range cell, so that propagation loss can be estimated. The second bound does not assume the target can be localized to a given range cell. The comparisons are carried...
Waveform design is studied for a multiple-input multiple-output over-the horizon (MIMO-OTH) radar system faced with a combination of additive Gaussian noise and signal dependent clutter. We define the waveform transmitted at each antenna as a weighted sum of a set of orthogonal sequences. Assume that different transmit antennas use the same set of orthogonal sequences, while the weighting factors...
While recent advances have provided extremely efficient distributed methods for computing optimal test statistics for many hypothesis testing problems occurring in large sensor networks, the popular multivariate Gaussian hypothesis testing problem involving a change in both the mean vector and covariance matrix is not one of these. The difficultly is that these test statistics generally require long...
