On the Adaptive Array Problem
Linköping University, Department of Electrical Engineering, Automatic Control. Linköping University, The Institute of Technology.
1987 (English)Licentiate thesis, monograph (Other academic)
Abstract [en]

By an array we mean a set of coupled sensors, typically antenna elements. The array receives superimposed signals from distant sources. By combining the outputs of the sensors in different ways, one can change the array sensitivity to different Directions-of-Arrival (DOA). It is thus possible to let some signals pass through while reflecting others. In this thesis we discuss the problem of separating a desired signal that is superimposed with undesired jamming signals and noise.

The optimal SNR (Signal to Noise Ratio) is given special attention. We include a discussion on what happens in a slowly time varying multipath environment.

The proposed methods are especially designed for radio communication system. We study three possibilites of separating between the received signals. These are; Methods using a reference signal, The case of known look direction and Time gated systems. We also include computer simulations to test the methods.
