Abstract :
Worldwide, microwave holographic metrology is being considered as a very powerful diagnostic tool for identifying reflector surface distortions and defective radiating elements of an array. Important measurement improvements, algorithm developments, error evaluations, and display methodologies have been reported in recent years. The author discusses the application of microwave holographic metrology to space communication antennas.<>
