Effect of error correlations and systematic errors on average array sidelobes
Abstract
The effect of error correlations on the average errorinduced sidelobe level of a planar array is studied. It is found that correlations among the random errors rapidly decrease the average errorsidelobe level (relative to the level when all errors are uncorrelated) as the correlation radius is increased. However, even though the average errorsidelobe level decreases, there are certain types of correlation that produce large local sidelobe increases. In particular, it is found that a onedimensional correlation produces a large ridge of sidelobes in the plane orthogonal to the direction of the correlation. Simple results are derived from both the amplitude and the angular width of this ridge.
