Abstract
The DSN microwave antenna holography project will obtain three-dimensional “pictures” of the large DSN antenna surfaces. These “pictures” must be of sufficient resolution to allow adjustment of the reflector panels to an rms surface of 0.5 mm (0.25 mm, goal). This article outlines the major parameters and equations needed to define a holographic measurement system and then discusses the proof of concept demonstration measurement that was made at DSS-43 (Australia) that resulted in contour maps with spatial resolution of 7m in the aperture plane and resolution orthogonal to the aperture plane of 0.7 mm.
