Abstract:

Two problems relating to the design of arrays for imaging complex fields are the sidelobe levels and the energy within those sidelobes. While designers often know the performance of a filled aperture, the much larger number of parameters involved in array design lead to great difficulty evaluating the performance level. This report describes a family of optical arrays whose parameters were evaluated by a computer analysis system. For simplicity all the arrays considered were in the same family a circular ring of evenly spaced array elements, so that comparisons could be made as the number of array elements was varied. Arrays with 3, 7, 15, and 27 elements were considered in detail, including the proper corrections for both finite element size and finite bandpass.
