Stochastic Error Modeling of Beamformer Output for Arrays with Directive Elements
Abstract
The error analysis at a two-dimensional passive array (conformal or planar) with directive element responses is developed. The analysis is presented for failures (both compensated and noncompensated), element phase errors, and element amplitude errors. The combination of these various mechanisms and their effect on mean beampattern power is given analytically. The report concludes with numerical examples of the errors, as well as with the analytical derivation of various physical error mechanisms in terms of amplitude and phase error. Although developed for conformal arrays of velocity sensors, the mathematical derivations in the analysis are general enough to apply to a wide variety of passive arrays.
