INVESTIGATION OF A MULTIPLE BEAM SCANNING CIRCULAR ARRAY

摘要

The final technical report and the preceding first scientific report have completely described the effort expended in the investigation and analysis of the multiplebeam cylindrical array concept. The theoretical and experimental effort expended on the program have proved that the fundamental concept is plausible and practical. The results achieved with the four-element and 16-element fixed frequency multiple-beam arrays were in general accordance with the predicted data. The 4 x 8 multiplebeam cylindrical array attested to the fact that multiple beams could be formed at a number of elevation stations simultaneously. The broad bandwidth experiment showed that beams could be formed over an octave in frequency range and indeed it is expected that this performance could be extended over much larger frequency ranges. The analysis contained in Section 5.0 of the report outlines a general design procedure for achieving a given level of performance with the cylindrical array.
