Paper Abstract

Methods are considered to improve performance of phased array systems by analyzing the effects of higher order aberrations on piston estimation and control. The analysis confirms that the use of wavefront sensor measurements to augment the piston sensor readings allow accurate estimation of the true piston difference in an edge sampling array. In addition, average phase at the sampler can be estimated very accurately even in the presence of WFS errors. Finally, using a three element phased array in an OTF non-redundant geometry, one can, after image reconstruction, significantly increase resolution compared to a single telescope of comparable entrance pupil area.
