Effects of annular-aperture receiver on angle-of-arrival fluctuations of plane waves.
We obtained an exact analytical solution of the annular-aperture averaged angle-of-arrival (AOA) variance for plane waves. The difference between the circular- and annular-aperture averaged AOA variance with the same values of the outer diameter is calculated, and the results show that the difference is no more than 3.12%, if the inner diameter is not larger than half the outer diameter.
