Abstract:

An antenna array using multiple beams for direction finding has certain inherent errors associated with its use. Two error expressions are utilized to give a measure of the accuracy obtained using this antenna system. One of these is called the maximum average error and the other the expected error. Five different operating conditions are investigated. They are 1 the ideal case, where all beams are assumed to have the same form 2 the unequal beamwidth case, where the effect of broadening the beam pattern when directed away from broadside is considered 3 the unequal gain, equal beamwidth case considers the effect of receiver gain imbalance 4 the unequal gain, unequal beamwidth case, which is a combination of the effects of 2 and 3 above and 5 the random signal detection case, which treats the problem of certain intercepts remaining undetected. Comparisons are made with the ideal case for all non-ideal operating conditions and are displayed in graphical form. The effect of beam broadening is shown to be quite small. Author
