Abstract :
We present an analysis of the interference coherence effects on the performance of an antenna array processor, which maximizes the output signal-to-noise ratio (SNR) for a coherent wave. The analytical expression for the optimal weight vector, directional pattern and output SNR is derived as a function of the coherence coefficient, interference power and parameters of the adaptive processor. We show how different models of interference coherence affect the array performance. Finally, to illustrate the theory, several numerical results are given
