Experimental demonstration of a 35 GHz holographic antenna
We have developed a novel two-dimensional grating antenna based on microwave holography. The two-dimensional grating (hologram) is formed on a dielectric substrate and fed by an integrated surface wave exciter. Various design issues will be presented, as will a 35 GHz demonstration prototype antenna designed, fabricated, and tested. Measured radiation patterns closely agreed with the theoretical prediction.

Hologram matrix and its application to a novel radar
The hologram matrix, which is a more elementary quantity than a conventional microwave hologram and contains much more information, is defined. Its application to a microwave holographic radar is described. This radar determines the distance by the spatial distribution of the scattered wave and differs from all other radars which determine the distance by the lapse of time. Some promising results were obtained from the computer simulation of such a radar.
