✦ Synopsis

Problems arise in providing excitation phases and amplitudes to individual antenna elements for wide-angle scanning by applying spherical array antennas for mobile satellite communications for ships, automobiles, and aircraft. These antennas do not have many antenna elements. Thus, emphasis is on obtaining the maximum gain rather than realizing the characteristics of low sidelobe levels.

We propose a dynamic technique for a microwa¨e holography system. We use a microstrip patch antenna in constructing the hologram and a new correlation method to reconstruct its digital form. The new reconstruction idea is based on the correlation between the hologram of point source and the hologram
