Adaptive Detection in Non-Stationary Interference, Part 3

Abstract

The analysis of Parts I and II of the report with this title has been extended into two directions. In the first case, the performance of an adaptive system with respect to signals arriving from directions other than the steering direction is evaluated. It is shown that these signals are reflected more strongly than would be suggested by the sidelobe levels of the adaptive patterns themselves. In the other case, the detection problem is generalized to include the detection of signals known only to lie in a subspace of the space of steering vectors. Again, performance is derived and the penalty associated with the greater uncertainty of the signal model is shown to be small. The analysis of Part I essentially repeated here, both to keep this report self-contained and to present an alternative version of the basic derivations. Keywords: Adaptive antennas; Signal to noise ratio; Maximum likelihood detection statistical hypothesis testing; Signal to noise ratio; Gaussian noise.
