Signal and interference levels in antenna array with optimum radiation pattern
Abstract
An antenna array is considered which has an optimum radiation pattern, with the minimum meansquare deviation of the vector of weight factors as the the optimality criterion and this vector described by the WienerHopf matrix equation. Power of the useful signal and total power of all interference signals in such an array are calculated on this basis, assuming mutually noncorrelated signal, interference, and thermal noise. The results reveal that signal power and interference power as well as combined output power all depended on the signalto(interferencenoise) ratio at the output. They also indicate the attainable power characteristics of such an antenna array.
