Abstract
|
We proposed efficient techniques for passive detection and localization of emitters of low probability of intercept signals. These are the generalized likelihood ration test (GLRT) detector and the maximum likelihood estimator (MLE). We derived the theoretical bounds for the localization variance, the Cramer-Rao lower bound (CRLB), and showed that the MLE attains the bounds. We further investigated the problems of optimal sensor configuration, knowledge aided geo-location design as well as method to improved the TDOA geo-location technique.
