By recording and reconstructing several microwave holograms of the same object at different frequencies, and superposition of the complex amplitude of the reconstruced images in an appropriate manner, the resolving power can considerably be improved. Experiments in the 8-12 GHz region are presented with simple objects. The reconstruction is done numerically on a digital computer.
