Paper Abstract

An algorithm for the accurate control of piston phase error and the equalization of path length differences of a multiline synthetic aperture transmitter is investigated. This algorithm uses the focal plane interference of two multiline rectangular beams. A parameter space is established which provides an unambiguous hill-climbing control system by generating a function of the piston phase error that increases monotonically and smoothly with pathelength error as the error decreases to zero. Both theoretical and experimental results are provided. The error incurred due to local subaperture tilt is also found.
