|Abstract:||This paper identifies a bound for the worst-case (largest) missed-detection and false-alarm probabilities for a chisquare monitor in which the input signal vector cannot be perfectly decorrelated. A new method for bounding monitor missed-detection performance is introduced that leverages the aspect ratio (ratio of maximum to minimum eigenvalue) for the covariance matrix of the imperfectly decorrelated signal. An application to signal deformation monitoring (SDM) for the global positioning system (GPS) indicates that the new bound is both tight and relatively inexpensive to compute.|
