Abstract

This work describes a new technique for the determination of antenna far field radiation patterns and the imaging of antenna fields from holographic intensity patterns. These intensity patterns are obtained by combining the sampled antenna near field with an electronically synthesised offset reference plane wave. The resultant intensity pattern can be recorded in a fast and inexpensive manner. This work also indicates that true 3D images can be reconstructed from the measured 2D intensity patterns.
